Postfix Standard Configuration ExamplesPostfix Standard Configuration ExamplesThis document presents a number of typical Postfix configurations. This document should be reviewed after you have followed the basic configuration steps as described in the BASIC_CONFIGURATION_README document. In particular, do not proceed here if you don't already have Postfix working for local mail submission and for local mail delivery.
The first part of this document presents standard configurations that each solve one specific problem.
The second part of this document presents additional configurations for hosts in specific environments.
Postfix should work out of the box without change on a stand-alone machine that has direct Internet access. At least, that is how Postfix installs when you download the Postfix source code via http://www.postfix.org/.
You can use the command "postconf -n" to find out what settings are overruled by your main.cf. Besides a few pathname settings, few parameters should be set on a stand-alone box, beyond what is covered in the BASIC_CONFIGURATION_README document:
/etc/postfix/main.cf: # Optional: send mail as user@@domainname instead of user@@hostname. #myorigin = $mydomain # Optional: specify NAT/proxy external address. #proxy_interfaces = 1.2.3.4 # Alternative 1: don't relay mail from other hosts. mynetworks_style = host relay_domains = # Alternative 2: relay mail from local clients only. # mynetworks = 192.168.1.0/28 # relay_domains =
See also the section "Postfix on hosts without a real Internet hostname" if this is applicable to your configuration.
A null client is a machine that can only send mail. It receives no mail from the network, and it does not deliver any mail locally. A null client typically uses POP, IMAP or NFS for mailbox access.
In this example we assume that the Internet domain name is "example.com" and that the machine is named "nullclient.example.com". As usual, the examples show only parameters that are not left at their default settings.
1 /etc/postfix/main.cf: 2 myorigin = $mydomain 3 relayhost = $mydomain 4 inet_interfaces = loopback-only 5 local_transport = error:local delivery is disabled 6 7 /etc/postfix/master.cf: 8 Comment out the local delivery agent entry
Translation:
Line 2: Send mail as "user@@example.com" (instead of "user@@nullclient.example.com"), so that nothing ever has a reason to send mail to "user@@nullclient.example.com".
Line 3: Forward all mail to the mail server that is responsible for the "example.com" domain. This prevents mail from getting stuck on the null client if it is turned off while some remote destination is unreachable.
Line 4: Do not accept mail from the network.
Lines 5-8: Disable local mail delivery. All mail goes to the mail server as specified in line 3.
This section describes a local area network environment of one main server and multiple other systems that send and receive email. As usual we assume that the Internet domain name is "example.com". All systems are configured to send mail as "user@@example.com", and all systems receive mail for "user@@hostname.example.com". The main server also receives mail for "user@@example.com". We call this machine by the name of mailhost.example.com.
A drawback of sending mail as "user@@example.com" is that mail for "root" and other system accounts is also sent to the central mailhost. See the section "Delivering some but not all accounts locally" below for possible solutions.
As usual, the examples show only parameters that are not left at their default settings.
First we present the non-mailhost configuration, because it is the simpler one. This machine sends mail as "user@@example.com" and is final destination for "user@@hostname.example.com".
1 /etc/postfix/main.cf: 2 myorigin = $mydomain 3 mynetworks = 127.0.0.0/8 10.0.0.0/24 4 relay_domains = 5 # Optional: forward all non-local mail to mailhost 6 #relayhost = $mydomain
Translation:
Line 2: Send mail as "user@@example.com".
Line 3: Specify the trusted networks.
Line 4: This host does not relay mail from untrusted networks.
Line 6: This is needed if no direct Internet access is available. See also below, "Postfix behind a firewall".
Next we present the mailhost configuration. This machine sends mail as "user@@example.com" and is final destination for "user@@hostname.example.com" as well as "user@@example.com".
1 DNS: 2 example.com IN MX 10 mailhost.example.com. 3 4 /etc/postfix/main.cf: 5 myorigin = $mydomain 6 mydestination = $myhostname localhost.$mydomain localhost $mydomain 7 mynetworks = 127.0.0.0/8 10.0.0.0/24 8 relay_domains = 9 # Optional: forward all non-local mail to firewall 10 #relayhost = [firewall.example.com]
Translation:
Line 2: Send mail for the domain "example.com" to the machine mailhost.example.com. Remember to specify the "." at the end of the line.
Line 5: Send mail as "user@@example.com".
Line 6: This host is the final mail destination for the "example.com" domain, in addition to the names of the machine itself.
Line 7: Specify the trusted networks.
Line 8: This host does not relay mail from untrusted networks.
Line 10: This is needed only when the mailhost has to forward non-local mail via a mail server on a firewall. The [] forces Postfix to do no MX record lookups.
In an environment like this, users access their mailbox in one or more of the following ways:
Mailbox access via NFS or equivalent.
Mailbox access via POP or IMAP.
Mailbox on the user's preferred machine.
In the latter case, each user has an alias on the mailhost that forwards mail to her preferred machine:
/etc/aliases:
joe: joe@@joes.preferred.machine
jane: jane@@janes.preferred.machine
On some systems the alias database is not in /etc/aliases. To find out the location for your system, execute the command "postconf alias_maps".
Execute the command "newaliases" whenever you change the aliases file.
The idea is to set up a Postfix email firewall/gateway that forwards mail for "example.com" to an inside gateway machine but rejects mail for "anything.example.com". There is only one problem: with "relay_domains = example.com", the firewall normally also accepts mail for "anything.example.com". That would not be right.
Note: this example requires Postfix version 2.0 and later. To find out what Postfix version you have, execute the command "postconf mail_version".
The solution is presented in multiple parts. This first part gets rid of local mail delivery on the firewall, making the firewall harder to break.
1 /etc/postfix/main.cf: 2 myorigin = example.com 3 mydestination = 4 local_recipient_maps = 5 local_transport = error:local mail delivery is disabled 6 7 /etc/postfix/master.cf: 8 Comment out the local delivery agent
Translation:
Line 2: Send mail from this machine as "user@@example.com", so that no reason exists to send mail to "user@@firewall.example.com".
Lines 3-8: Disable local mail delivery on the firewall machine.
For the sake of technical correctness the firewall must be able to receive mail for postmaster@@[firewall ip address]. Reportedly, some things actually expect this ability to exist. The second part of the solution therefore adds support for postmaster@@[firewall ip address], and as a bonus we do abuse@@[firewall ip address] as well. All the mail to these two accounts is forwarded to an inside address.
1 /etc/postfix/main.cf: 2 virtual_alias_maps = hash:/etc/postfix/virtual 3 4 /etc/postfix/virtual: 5 postmaster postmaster@@example.com 6 abuse abuse@@example.com
Translation:
Because mydestination is empty (see the previous example), only address literals matching $inet_interfaces or $proxy_interfaces are deemed local. So "localpart@@[a.d.d.r]" can be matched as simply "localpart" in canonical(5) and virtual(5). This avoids the need to specify firewall IP addresses into Postfix configuration files.
The last part of the solution does the email forwarding, which is the real purpose of the firewall email function.
1 /etc/postfix/main.cf: 2 mynetworks = 127.0.0.0/8 12.34.56.0/24 3 relay_domains = example.com 4 parent_domain_matches_subdomains = 5 debug_peer_list smtpd_access_maps 6 smtpd_recipient_restrictions = 7 permit_mynetworks reject_unauth_destination 8 9 relay_recipient_maps = hash:/etc/postfix/relay_recipients 10 transport_maps = hash:/etc/postfix/transport 11 12 /etc/postfix/relay_recipients: 13 user1@@example.com x 14 user2@@example.com x 15 . . . 16 17 /etc/postfix/transport: 18 example.com smtp:[inside-gateway.example.com]
Translation:
Lines 1-7: Accept mail from local systems in $mynetworks, and accept mail from outside for "user@@example.com" but not for "user@@anything.example.com". The magic is in lines 4-5.
Lines 9, 12-14: Define the list of valid addresses in the "example.com" domain that can receive mail from the Internet. This prevents the mail queue from filling up with undeliverable MAILER-DAEMON messages. If you can't maintain a list of valid recipients then you must specify "relay_recipient_maps =" (that is, an empty value), or you must specify an "@@example.com x" wild-card in the relay_recipients table.
Lines 10, 17-18: Route mail for "example.com" to the inside gateway machine. The [] forces Postfix to do no MX lookup.
Specify dbm instead of hash if your system uses dbm files instead of db files. To find out what lookup tables Postfix supports, use the command "postconf -m".
Execute the command "postmap /etc/postfix/relay_recipients" whenever you change the relay_recipients table.
Execute the command "postmap /etc/postfix/transport" whenever you change the transport table.
In some installations, there may be separate instances of Postfix processing inbound and outbound mail on a multi-homed firewall. The inbound Postfix instance has an SMTP server listening on the external firewall interface, and the outbound Postfix instance has an SMTP server listening on the internal interface. In such a configuration is it is tempting to configure $inet_interfaces in each instance with just the corresponding interface address.
In most cases, using inet_interfaces in this way will not work, because as documented in the $inet_interfaces reference manual, the smtp(8) delivery agent will also use the specified interface address as the source address for outbound connections and will be unable to reach hosts on "the other side" of the firewall. The symptoms are that the firewall is unable to connect to hosts that are in fact up. See the inet_interfaces parameter documentation for suggested work-arounds.
A drawback of sending mail as "user@@example.com" (instead of "user@@hostname.example.com") is that mail for "root" and other system accounts is also sent to the central mailhost. In order to deliver such accounts locally, you can set up virtual aliases as follows:
1 /etc/postfix/main.cf: 2 virtual_alias_maps = hash:/etc/postfix/virtual 3 4 /etc/postfix/virtual: 5 root root@@localhost 6 . . .
Translation:
Line 5: As described in the virtual(5) manual page, the bare name "root" matches "root@@site" when "site" is equal to $myorigin, when "site" is listed in $mydestination, or when it matches $inet_interfaces or $proxy_interfaces.
The simplest way to set up Postfix on a host behind a firewalled network is to send all mail to a gateway host, and to let that mail host take care of internal and external forwarding. Examples of that are shown in the local area network section above. A more sophisticated approach is to send only external mail to the gateway host, and to send intranet mail directly. That's what Wietse does at work.
Note: this example requires Postfix version 2.0 and later. To find out what Postfix version you have, execute the command "postconf mail_version".
The following example presents additional configuration. You need to combine this with basic configuration information as discussed the first half of this document.
1 /etc/postfix/main.cf: 2 transport_maps = hash:/etc/postfix/transport 3 relayhost = 4 # Optional for a machine that isn't "always on" 5 #fallback_relay = [gateway.example.com] 6 7 /etc/postfix/transport: 8 # Internal delivery. 9 example.com : 10 .example.com : 11 # External delivery. 12 * smtp:[gateway.example.com]
Translation:
Lines 2, 7-12: Request that intranet mail is delivered directly, and that external mail is given to a gateway. Obviously, this example assumes that the organization uses DNS MX records internally. The [] forces Postfix to do no MX lookup.
Line 5: This prevents mail from being stuck in the queue when the machine is turned off. Postfix tries to deliver mail directly, and gives undeliverable mail to a gateway.
Specify dbm instead of hash if your system uses dbm files instead of db files. To find out what lookup tables Postfix supports, use the command "postconf -m".
Execute the command "postmap /etc/postfix/transport" whenever you edit the transport table.
This section presents additional configuration. You need to combine this with basic configuration information as discussed the first half of this document.
When your system is SECONDARY MX host for a remote site this is all you need:
1 DNS: 2 the.backed-up.domain.tld IN MX 100 your.machine.tld. 3 4 /etc/postfix/main.cf: 5 relay_domains = . . . the.backed-up.domain.tld 6 smtpd_recipient_restrictions = 7 permit_mynetworks reject_unauth_destination 8 9 # You must specify your NAT/proxy external address. 10 #proxy_interfaces = 1.2.3.4 11 12 relay_recipient_maps = hash:/etc/postfix/relay_recipients 13 14 /etc/postfix/relay_recipients: 15 user1@@the.backed-up.domain.tld x 16 user2@@the.backed-up.domain.tld x 17 . . .
When your system is PRIMARY MX host for a remote site you need the above, plus:
18 /etc/postfix/main.cf: 19 transport_maps = hash:/etc/postfix/transport 20 21 /etc/postfix/transport: 22 the.backed-up.domain.tld relay:[their.mail.host.tld]
Important notes:
Do not list the.backed-up.domain.tld in mydestination.
Do not list the.backed-up.domain.tld in virtual_alias_domains.
Do not list the.backed-up.domain.tld in virtual_mailbox_domains.
Lines 1-7: Forward mail from the Internet for "the.backed-up.domain.tld" to the primary MX host for that domain.
Line 10: This is a must if Postfix receives mail via a NAT relay or proxy that presents a different IP address to the world than the local machine.
Lines 12-16: Define the list of valid addresses in the "the.backed-up.domain.tld" domain. This prevents your mail queue from filling up with undeliverable MAILER-DAEMON messages. If you can't maintain a list of valid recipients then you must specify "relay_recipient_maps =" (that is, an empty value), or you must specify an "@@the.backed-up.domain.tld x" wild-card in the relay_recipients table.
Line 22: The [] forces Postfix to do no MX lookup.
Specify dbm instead of hash if your system uses dbm files instead of db files. To find out what lookup tables Postfix supports, use the command "postconf -m".
Execute the command "postmap /etc/postfix/transport" whenever you change the transport table.
NOTE for Postfix < 2.2: Do not use the fallback_relay feature when relaying mail for a backup or primary MX domain. Mail would loop between the Postfix MX host and the fallback_relay host when the final destination is unavailable.
These are default settings in Postfix version 2.2 and later.
This section applies to dialup connections that are down most of the time. For dialup connections that are up 24x7, see the local area network section above.
This section presents additional configuration. You need to combine this with basic configuration information as discussed the first half of this document.
If you do not have your own hostname and IP address (usually with dialup, cable TV or DSL connections) then you should also study the section on "Postfix on hosts without a real Internet hostname".
If your machine is disconnected most of the time, there isn't a lot of opportunity for Postfix to deliver mail to hard-to-reach corners of the Internet. It's better to give the mail to a machine that is connected all the time. In the example below, the [] prevents Postfix from trying to look up DNS MX records.
/etc/postfix/main.cf: relayhost = [smtprelay.someprovider.com]
Disable spontaneous SMTP mail delivery (if using on-demand dialup IP only).
Normally, Postfix attempts to deliver outbound mail at its convenience. If your machine uses on-demand dialup IP, this causes your system to place a telephone call whenever you submit new mail, and whenever Postfix retries to deliver delayed mail. To prevent such telephone calls from being placed, disable spontaneous SMTP mail deliveries.
/etc/postfix/main.cf: defer_transports = smtp (Only for on-demand dialup IP hosts)
Disable SMTP client DNS lookups (dialup LAN only).
/etc/postfix/main.cf: disable_dns_lookups = yes (Only for on-demand dialup IP hosts)
Put the following command into your PPP or SLIP dialup scripts:
/usr/sbin/sendmail -q (whenever the Internet link is up)
The exact location of the Postfix sendmail command is system-specific. Use the command "postconf sendmail_path" to find out where the Postfix sendmail command is located on your machine.
In order to find out if the mail queue is flushed, use something like:
#!/bin/sh
# Start mail deliveries.
/usr/sbin/sendmail -q
# Allow deliveries to start.
sleep 10
# Loop until all messages have been tried at least once.
while mailq | grep '^[^ ]*\*' >/dev/null
do
sleep 10
done
If you have disabled spontaneous SMTP mail delivery, you also need to run the "sendmail -q" command every now and then while the dialup link is up, so that newly-posted mail is flushed from the queue.
This section is for hosts that don't have their own Internet hostname. Typically these are systems that get a dynamic IP address via DHCP or via dialup. Postfix will let you send and receive mail just fine between accounts on a machine with a fantasy name. However, you cannot use a fantasy hostname in your email address when sending mail into the Internet, because no-one would be able to reply to your mail. In fact, more and more sites refuse mail addresses with non-existent domain names.
Note: the following information is Postfix version dependent. To find out what Postfix version you have, execute the command "postconf mail_version".
Postfix 2.2 uses the generic(5) address mapping to replace local fantasy email addresses by valid Internet addresses. This mapping happens ONLY when mail leaves the machine; not when you send mail between users on the same machine.
The following example presents additional configuration. You need to combine this with basic configuration information as discussed the first half of this document.
1 /etc/postfix/main.cf: 2 smtp_generic_maps = hash:/etc/postfix/generic 3 4 /etc/postfix/generic: 5 his@@localdomain.local hisaccount@@hisisp.example 6 her@@localdomain.local heraccount@@herisp.example 7 @@localdomain.local hisaccount+local@@hisisp.example
When mail is sent to a remote host via SMTP:
Line 5 replaces his@@localdomain.local by his ISP mail address,
Line 6 replaces her@@localdomain.local by her ISP mail address, and
Line 7 replaces other local addresses by his ISP account, with an address extension of +local (this example assumes that the ISP supports "+" style address extensions).
Specify dbm instead of hash if your system uses dbm files instead of db files. To find out what lookup tables Postfix supports, use the command "postconf -m".
Execute the command "postmap /etc/postfix/generic" whenever you change the generic table.
The solution with older Postfix systems is to use valid Internet addresses where possible, and to let Postfix map valid Internet addresses to local fantasy addresses. With this, you can send mail to the Internet and to local fantasy addresses, including mail to local fantasy addresses that don't have a valid Internet address of their own.
The following example presents additional configuration. You need to combine this with basic configuration information as discussed the first half of this document.
1 /etc/postfix/main.cf: 2 myhostname = hostname.localdomain 3 mydomain = localdomain 4 5 canonical_maps = hash:/etc/postfix/canonical 6 7 virtual_alias_maps = hash:/etc/postfix/virtual 8 9 /etc/postfix/canonical: 10 your-login-name your-account@@your-isp.com 11 12 /etc/postfix/virtual: 13 your-account@@your-isp.com your-login-name
Translation:
Lines 2-3: Substitute your fantasy hostname here. Do not use a domain name that is already in use by real organizations on the Internet. See RFC 2606 for examples of domain names that are guaranteed not to be owned by anyone.
Lines 5, 9, 10: This provides the mapping from "your-login-name@@hostname.localdomain" to "your-account@@your-isp.com". This part is required.
Lines 7, 12, 13: Deliver mail for "your-account@@your-isp.com" locally, instead of sending it to the ISP. This part is not required but is convenient.
Specify dbm instead of hash if your system uses dbm files instead of db files. To find out what lookup tables Postfix supports, use the command "postconf -m".
Execute the command "postmap /etc/postfix/canonical" whenever you change the canonical table.
Execute the command "postmap /etc/postfix/virtual" whenever you change the virtual table.
@ 1.1.1.1 log @Import Postfix 2.6.2. @ text @@ 1.1.1.2 log @Import Postfix 2.7.1. Major changes since Postfix 2.6.6: - Improved before-queue content filter performance. With "smtpd_proxy_options = speed_adjust", the Postfix SMTP server receives the entire message before it connects to a before-queue content filter. Typically, this allows Postfix to handle the same mail load with fewer content filter processes. - Improved address verification performance. The verify database is now persistent by default, and it is automatically cleaned periodically. Under overload conditions, the Postfix SMTP server no longer waits up to 6 seconds for an address probe to complete. - Support for reputation management based on the local SMTP client IP address. This is typically implemented with "FILTER transportname:" actions in access maps or header/body checks, and mail delivery transports in master.cf with unique smtp_bind_address values. @ text @d322 1 a322 1 4 /etc/postfix/virtual: d428 1 a428 1 4 /etc/postfix/virtual: a444 3Execute the command "postmap /etc/postfix/virtual" after editing the file.

@ 1.1.1.4 log @Import Postfix 2.10.2. Major changes since version 2.9.* are: - Separation of relay policy (with smtpd_relay_restrictions) from spam policy (with smtpd_{client, helo, sender, recipient}_restrictions), which makes accidental open relay configuration less likely. The default is backwards compatible. - HAproxy load-balancer support for postscreen(8) and smtpd(8). The nginx proxy was already supported by Postfix 2.9 smtpd(8), using XCLIENT commands. - Support for the TLSv1 and TLSv2 protocols, as well as support to turn them off if needed for inter-operability. - Laptop-friendly configuration. By default, Postfix now uses UNIX-domain sockets instead of FIFOs, and thus avoids MTIME file system updates on an idle mail system. - Revised postconf(1) command. The "-x" option expands $name in a parameter value (both main.cf and master.cf); the "-o name=value" option overrides a main.cf parameter setting; and postconf(1) now warns about a $name that has no name=value setting. - Sendmail-style "socketmap" lookup tables. @ text @d105 1 a105 1 "example.com" and that the machine is named "hostname.example.com". d112 7 a118 5 2 myhostname = hostname.example.com 3 myorigin = $mydomain 4 relayhost = $mydomain 5 inet_interfaces = loopback-only 6 mydestination = d126 3 a128 8Line 2: Set myhostname to hostname.example.com, in case the machine name isn't set to a fully-qualified domain name (use the command "postconf -d myhostname" to find out what the machine name is).
Line 2: The myhostname value also provides the default value for the mydomain parameter (here, "mydomain = example.com").
d130 1 a130 5Line 3: Send mail as "user@@example.com" (instead of "user@@hostname.example.com"), so that nothing ever has a reason to send mail to "user@@hostname.example.com".

The main changes since version 2.10.* are: - Support for PKI-less TLS server certificate verification with DANE (DNS-based Authentication of Named Entities) where the CA public key or the server certificate is identified via DNSSEC lookup. This requires a DNS resolver that validates DNSSEC replies. The problem with conventional PKI is that there are literally hundreds of organizations world-wide that can provide a certificate in anyone's name. DANE limits trust to the people who control the target DNS zone and its parent zones. - A new postscreen_dnsbl_whitelist_threshold feature to allow clients to skip postscreen tests based on their DNSBL score. This can eliminate email delays due to "after 220 greeting" protocol tests, which otherwise require that a client reconnects before it can deliver mail. Some providers such as Google don't retry from the same IP address, and that can result in large email delivery delays. - The recipient_delimiter feature now supports different delimiters, for example both "+" and "-". As before, this implementation recognizes exactly one delimiter character per email address, and exactly one address extension per email address. - Advanced master.cf query/update support to access service attributes as "name = value" pairs. For example to turn off chroot on all services use "postconf -F '*/*/chroot = n'", and to change/add a "-o name=value" setting use "postconf -P 'smtp/inet/name = value'". This was developed primarily to allow automated tools to manage Postfix systems without having to parse Postfix configuration files. @ text @d328 1 a328 1 2 virtual_alias_maps =

The stable Postfix release is called postfix-3.7.x where 3=major release number, 7=minor release number, x=patchlevel. The stable release never changes except for patches that address bugs or emergencies. Patches change the patchlevel and the release date. New features are developed in snapshot releases. These are called postfix-3.8-yyyymmdd where yyyymmdd is the release date (yyyy=year, mm=month, dd=day). Patches are never issued for snapshot releases; instead, a new snapshot is released. The mail_release_date configuration parameter (format: yyyymmdd) specifies the release date of a stable release or snapshot release. If you upgrade from Postfix 3.5 or earlier, read RELEASE_NOTES-3.6 before proceeding.

Bugfix for messages not delivered after "warning: Unexpected record type 'X' ============================================================================ Due to a bug introduced in Postfix 3.7.0, a message could falsely be flagged as corrupt with "warning: Unexpected record type 'X'". Such messages were moved to the "corrupt" queue directory, where they may still be found. See below for instructions to deal with these falsely flagged messages. This could happen for messages with 5000 or more recipients, or with fewer recipients on a busy mail server. The problem was first reported by Frank Brendel, reproduced by John Alex.

This daemon is not exposed to local or remote users. Found by Claude Opus 4.6. Bugfix (defect introduced: 20260309) a change, to set the service_name default value to "amnesiac", violated a test that parameter names in postconf output must match 1:1 with parameter names in the postlink script. Changes in 3.11.1 Bugfix (defect introduced: 20260219): alias_maps errors when default_database_type was not set in main.cf. Fix by Michael Tokarev. Bugfix (defect introduced: Postfix 3.0): buffer over-read when Postfix is configured with an enhanced status code not followed by other text. For example, "5.7.2" without text after the three-number code, in an access(5) table, header or body checks, or with "$rbl_code $rbl_text" in rbl_reply_maps or default_rbl_reply. These are all uncommon configurations. Problem reported by Kamil Frankowicz. Bugfix (defect introduced: Postfix 3.3): null pointer in nbdb_reindexd(8) because the "service_name" value was not propagated. Report by Michael Tokarev. During Postfix start-up, avoid a spurious error message from nbdb_reindexd(8), when non_bdb_migration_level disables automatic re-indexing. Changes in 3.11.0 Postfix stable release 3.11.0 is available. Postfix 3.7 - 3.10 were updated a few weeks ago; after that, Postfix 3.7 will no longer be updated. The main changes are below. See the RELEASE_NOTES file for further details. Berkeley DB migration: Some (Linux) distributions are removing support for BerkeleyDB databases (In Postfix, this means we lose support for the hash: and btree: lookup tables). See NON_BERKELEYDB_README for manual and partially automatic migration from btree: to lmdb:, and from hash: to lmdb: or cdb:. The loss of BerkeleyDB affects Mailman versions that want to execute commands like "postmap hash:/path/to/file" when a mailing list is added or removed. Postfix provides a way to redirect such commands to a supported database type. You don't have to wait until BerkeleyDB support is removed. It can make sense to migrate while BerkeleyDB support is still available (mainly, less downtime). Changes in TLS support: Default TLS security. The Postfix SMTP client smtp_tls_security_level default value is "may" if Postfix was built with TLS support, and the compatibility_level is 3.11 or higher. Support for the RFC 8689 "REQUIRETLS" verb in ESMTP. This requires that every SMTP (and LMTP) server in the forward path is strongly authenticated with DANE, STS, or equivalent, and that every server announces REQUIRETLS support. See REQUIRETLS_README for suggestions to carefully enforce REQUIRETLS without causing massive mail delivery problems. Logging the TLS security level. This shows the desired and actual TLS security level enforcement status and, if a message requests REQUIRETLS, the REQUIRETLS policy enforcement status. For a list of examples see smtp_log_tls_feature_status Workaround for an interface mismatch between the Postfix SMTP client and MTA-STS policy plugins. This introduces a new parameter smtp_tls_enforce_sts_mx_patterns (default: "yes"). The MTA-STS plugin configuration needs to enable TLSRPT support, so that it forwards STS policy attributes to Postfix. Both postfix-tlspol and postfix-mta-sts-resolver have been updated accordingly. With this, the Postfix SMTP client will connect to an MX host only if its name matches any STS policy MX host pattern, and will match a server certificate against the MX hostname. Otherwise, the old behavior stays in effect: connect to any MX host listed in DNS, and match a server certificate against any STS policy MX host pattern. Post-quantum cryptography support. With OpenSSL 3.5 and later, change the tls_eecdh_auto_curves default value to avoid problems with network infrastructure that mishandles TLS hello messages larger than one (Ethernet) TCP segment. This problem is more generally known as "protocol ossification". Miscellaneous changes: Deprecation of obsolete parameters. Postfix programs log a warning that these parameters will be removed. See DEPRECATION_README for a list of deprecated parameters. JSON output support with "postconf -j|-jM|-jF|-jP", "postalias -jq|-js", "postmap -jq|-js", and "postmulti -jl". No support is planned for JSON input support. Milter support: improved Milter error handling for messages that arrive over a long-lived SMTP connection, by changing the default milter_default_action from "tempfail" to the new "shutdown" action (i.e. disconnect the remote SMTP client). This was already back-ported to earlier stable releases.

This document should be reviewed after you have followed the basic configuration steps as described in the BASIC_CONFIGURATION_README document. In particular, do not proceed here if you don't already have Postfix working for local mail submission and for local mail delivery.
The first part of this document presents standard configurations that each solve one specific problem.
The second part of this document presents additional configurations for hosts in specific environments.
Postfix should work out of the box without change on a stand-alone machine that has direct Internet access. At least, that is how Postfix installs when you download the Postfix source code via http://www.postfix.org/.
You can use the command "postconf -n" to find out what settings are overruled by your main.cf. Besides a few pathname settings, few parameters should be set on a stand-alone box, beyond what is covered in the BASIC_CONFIGURATION_README document:
/etc/postfix/main.cf: # Optional: send mail as user@@domainname instead of user@@hostname. #myorigin = $mydomain # Optional: specify NAT/proxy external address. #proxy_interfaces = 1.2.3.4 # Alternative 1: don't relay mail from other hosts. mynetworks_style = host relay_domains = # Alternative 2: relay mail from local clients only. # mynetworks = 192.168.1.0/28 # relay_domains =
See also the section "Postfix on hosts without a real Internet hostname" if this is applicable to your configuration.
A null client is a machine that can only send mail. It receives no mail from the network, and it does not deliver any mail locally. A null client typically uses POP, IMAP or NFS for mailbox access.
In this example we assume that the Internet domain name is "example.com" and that the machine is named "nullclient.example.com". As usual, the examples show only parameters that are not left at their default settings.
1 /etc/postfix/main.cf: 2 myorigin = $mydomain 3 relayhost = $mydomain 4 inet_interfaces = loopback-only 5 local_transport = error:local delivery is disabled 6 7 /etc/postfix/master.cf: 8 Comment out the local delivery agent entry
Translation:
Line 2: Send mail as "user@@example.com" (instead of "user@@nullclient.example.com"), so that nothing ever has a reason to send mail to "user@@nullclient.example.com".
Line 3: Forward all mail to the mail server that is responsible for the "example.com" domain. This prevents mail from getting stuck on the null client if it is turned off while some remote destination is unreachable.
Line 4: Do not accept mail from the network.
Lines 5-8: Disable local mail delivery. All mail goes to the mail server as specified in line 3.
This section describes a local area network environment of one main server and multiple other systems that send and receive email. As usual we assume that the Internet domain name is "example.com". All systems are configured to send mail as "user@@example.com", and all systems receive mail for "user@@hostname.example.com". The main server also receives mail for "user@@example.com". We call this machine by the name of mailhost.example.com.
A drawback of sending mail as "user@@example.com" is that mail for "root" and other system accounts is also sent to the central mailhost. See the section "Delivering some but not all accounts locally" below for possible solutions.
As usual, the examples show only parameters that are not left at their default settings.
First we present the non-mailhost configuration, because it is the simpler one. This machine sends mail as "user@@example.com" and is final destination for "user@@hostname.example.com".
1 /etc/postfix/main.cf: 2 myorigin = $mydomain 3 mynetworks = 127.0.0.0/8 10.0.0.0/24 4 relay_domains = 5 # Optional: forward all non-local mail to mailhost 6 #relayhost = $mydomain
Translation:
Line 2: Send mail as "user@@example.com".
Line 3: Specify the trusted networks.
Line 4: This host does not relay mail from untrusted networks.
Line 6: This is needed if no direct Internet access is available. See also below, "Postfix behind a firewall".
Next we present the mailhost configuration. This machine sends mail as "user@@example.com" and is final destination for "user@@hostname.example.com" as well as "user@@example.com".
1 DNS: 2 example.com IN MX 10 mailhost.example.com. 3 4 /etc/postfix/main.cf: 5 myorigin = $mydomain 6 mydestination = $myhostname localhost.$mydomain localhost $mydomain 7 mynetworks = 127.0.0.0/8 10.0.0.0/24 8 relay_domains = 9 # Optional: forward all non-local mail to firewall 10 #relayhost = [firewall.example.com]
Translation:
Line 2: Send mail for the domain "example.com" to the machine mailhost.example.com. Remember to specify the "." at the end of the line.
Line 5: Send mail as "user@@example.com".
Line 6: This host is the final mail destination for the "example.com" domain, in addition to the names of the machine itself.
Line 7: Specify the trusted networks.
Line 8: This host does not relay mail from untrusted networks.
Line 10: This is needed only when the mailhost has to forward non-local mail via a mail server on a firewall. The [] forces Postfix to do no MX record lookups.
In an environment like this, users access their mailbox in one or more of the following ways:
Mailbox access via NFS or equivalent.
Mailbox access via POP or IMAP.
Mailbox on the user's preferred machine.
In the latter case, each user has an alias on the mailhost that forwards mail to her preferred machine:
/etc/aliases:
joe: joe@@joes.preferred.machine
jane: jane@@janes.preferred.machine
On some systems the alias database is not in /etc/aliases. To find out the location for your system, execute the command "postconf alias_maps".
Execute the command "newaliases" whenever you change the aliases file.
The idea is to set up a Postfix email firewall/gateway that forwards mail for "example.com" to an inside gateway machine but rejects mail for "anything.example.com". There is only one problem: with "relay_domains = example.com", the firewall normally also accepts mail for "anything.example.com". That would not be right.
Note: this example requires Postfix version 2.0 and later. To find out what Postfix version you have, execute the command "postconf mail_version".
The solution is presented in multiple parts. This first part gets rid of local mail delivery on the firewall, making the firewall harder to break.
1 /etc/postfix/main.cf: 2 myorigin = example.com 3 mydestination = 4 local_recipient_maps = 5 local_transport = error:local mail delivery is disabled 6 7 /etc/postfix/master.cf: 8 Comment out the local delivery agent
Translation:
Line 2: Send mail from this machine as "user@@example.com", so that no reason exists to send mail to "user@@firewall.example.com".
Lines 3-8: Disable local mail delivery on the firewall machine.
For the sake of technical correctness the firewall must be able to receive mail for postmaster@@[firewall ip address]. Reportedly, some things actually expect this ability to exist. The second part of the solution therefore adds support for postmaster@@[firewall ip address], and as a bonus we do abuse@@[firewall ip address] as well. All the mail to these two accounts is forwarded to an inside address.
1 /etc/postfix/main.cf: 2 virtual_alias_maps = hash:/etc/postfix/virtual 3 4 /etc/postfix/virtual: 5 postmaster postmaster@@example.com 6 abuse abuse@@example.com
Translation:
Because mydestination is empty (see the previous example), only address literals matching $inet_interfaces or $proxy_interfaces are deemed local. So "localpart@@[a.d.d.r]" can be matched as simply "localpart" in canonical(5) and virtual(5). This avoids the need to specify firewall IP addresses into Postfix configuration files.
The last part of the solution does the email forwarding, which is the real purpose of the firewall email function.
1 /etc/postfix/main.cf: 2 mynetworks = 127.0.0.0/8 12.34.56.0/24 3 relay_domains = example.com 4 parent_domain_matches_subdomains = 5 debug_peer_list smtpd_access_maps 6 smtpd_recipient_restrictions = 7 permit_mynetworks reject_unauth_destination 8 9 relay_recipient_maps = hash:/etc/postfix/relay_recipients 10 transport_maps = hash:/etc/postfix/transport 11 12 /etc/postfix/relay_recipients: 13 user1@@example.com x 14 user2@@example.com x 15 . . . 16 17 /etc/postfix/transport: 18 example.com smtp:[inside-gateway.example.com]
Translation:
Lines 1-7: Accept mail from local systems in $mynetworks, and accept mail from outside for "user@@example.com" but not for "user@@anything.example.com". The magic is in lines 4-5.
Lines 9, 12-14: Define the list of valid addresses in the "example.com" domain that can receive mail from the Internet. This prevents the mail queue from filling up with undeliverable MAILER-DAEMON messages. If you can't maintain a list of valid recipients then you must specify "relay_recipient_maps =" (that is, an empty value), or you must specify an "@@example.com x" wild-card in the relay_recipients table.
Lines 10, 17-18: Route mail for "example.com" to the inside gateway machine. The [] forces Postfix to do no MX lookup.
Specify dbm instead of hash if your system uses dbm files instead of db files. To find out what lookup tables Postfix supports, use the command "postconf -m".
Execute the command "postmap /etc/postfix/relay_recipients" whenever you change the relay_recipients table.
Execute the command "postmap /etc/postfix/transport" whenever you change the transport table.
In some installations, there may be separate instances of Postfix processing inbound and outbound mail on a multi-homed firewall. The inbound Postfix instance has an SMTP server listening on the external firewall interface, and the outbound Postfix instance has an SMTP server listening on the internal interface. In such a configuration is it is tempting to configure $inet_interfaces in each instance with just the corresponding interface address.
In most cases, using inet_interfaces in this way will not work, because as documented in the $inet_interfaces reference manual, the smtp(8) delivery agent will also use the specified interface address as the source address for outbound connections and will be unable to reach hosts on "the other side" of the firewall. The symptoms are that the firewall is unable to connect to hosts that are in fact up. See the inet_interfaces parameter documentation for suggested work-arounds.
A drawback of sending mail as "user@@example.com" (instead of "user@@hostname.example.com") is that mail for "root" and other system accounts is also sent to the central mailhost. In order to deliver such accounts locally, you can set up virtual aliases as follows:
1 /etc/postfix/main.cf: 2 virtual_alias_maps = hash:/etc/postfix/virtual 3 4 /etc/postfix/virtual: 5 root root@@localhost 6 . . .
Translation:
Line 5: As described in the virtual(5) manual page, the bare name "root" matches "root@@site" when "site" is equal to $myorigin, when "site" is listed in $mydestination, or when it matches $inet_interfaces or $proxy_interfaces.
The simplest way to set up Postfix on a host behind a firewalled network is to send all mail to a gateway host, and to let that mail host take care of internal and external forwarding. Examples of that are shown in the local area network section above. A more sophisticated approach is to send only external mail to the gateway host, and to send intranet mail directly. That's what Wietse does at work.
Note: this example requires Postfix version 2.0 and later. To find out what Postfix version you have, execute the command "postconf mail_version".
The following example presents additional configuration. You need to combine this with basic configuration information as discussed the first half of this document.
1 /etc/postfix/main.cf: 2 transport_maps = hash:/etc/postfix/transport 3 relayhost = 4 # Optional for a machine that isn't "always on" 5 #fallback_relay = [gateway.example.com] 6 7 /etc/postfix/transport: 8 # Internal delivery. 9 example.com : 10 .example.com : 11 # External delivery. 12 * smtp:[gateway.example.com]
Translation:
Lines 2, 7-12: Request that intranet mail is delivered directly, and that external mail is given to a gateway. Obviously, this example assumes that the organization uses DNS MX records internally. The [] forces Postfix to do no MX lookup.
Line 5: This prevents mail from being stuck in the queue when the machine is turned off. Postfix tries to deliver mail directly, and gives undeliverable mail to a gateway.
Specify dbm instead of hash if your system uses dbm files instead of db files. To find out what lookup tables Postfix supports, use the command "postconf -m".
Execute the command "postmap /etc/postfix/transport" whenever you edit the transport table.
This section presents additional configuration. You need to combine this with basic configuration information as discussed the first half of this document.
When your system is SECONDARY MX host for a remote site this is all you need:
1 DNS: 2 the.backed-up.domain.tld IN MX 100 your.machine.tld. 3 4 /etc/postfix/main.cf: 5 relay_domains = . . . the.backed-up.domain.tld 6 smtpd_recipient_restrictions = 7 permit_mynetworks reject_unauth_destination 8 9 # You must specify your NAT/proxy external address. 10 #proxy_interfaces = 1.2.3.4 11 12 relay_recipient_maps = hash:/etc/postfix/relay_recipients 13 14 /etc/postfix/relay_recipients: 15 user1@@the.backed-up.domain.tld x 16 user2@@the.backed-up.domain.tld x 17 . . .
When your system is PRIMARY MX host for a remote site you need the above, plus:
18 /etc/postfix/main.cf: 19 transport_maps = hash:/etc/postfix/transport 20 21 /etc/postfix/transport: 22 the.backed-up.domain.tld relay:[their.mail.host.tld]
Important notes:
Do not list the.backed-up.domain.tld in mydestination.
Do not list the.backed-up.domain.tld in virtual_alias_domains.
Do not list the.backed-up.domain.tld in virtual_mailbox_domains.
Lines 1-7: Forward mail from the Internet for "the.backed-up.domain.tld" to the primary MX host for that domain.
Line 10: This is a must if Postfix receives mail via a NAT relay or proxy that presents a different IP address to the world than the local machine.
Lines 12-16: Define the list of valid addresses in the "the.backed-up.domain.tld" domain. This prevents your mail queue from filling up with undeliverable MAILER-DAEMON messages. If you can't maintain a list of valid recipients then you must specify "relay_recipient_maps =" (that is, an empty value), or you must specify an "@@the.backed-up.domain.tld x" wild-card in the relay_recipients table.
Line 22: The [] forces Postfix to do no MX lookup.
Specify dbm instead of hash if your system uses dbm files instead of db files. To find out what lookup tables Postfix supports, use the command "postconf -m".
Execute the command "postmap /etc/postfix/transport" whenever you change the transport table.
NOTE for Postfix < 2.2: Do not use the fallback_relay feature when relaying mail for a backup or primary MX domain. Mail would loop between the Postfix MX host and the fallback_relay host when the final destination is unavailable.
These are default settings in Postfix version 2.2 and later.
This section applies to dialup connections that are down most of the time. For dialup connections that are up 24x7, see the local area network section above.
This section presents additional configuration. You need to combine this with basic configuration information as discussed the first half of this document.
If you do not have your own hostname and IP address (usually with dialup, cable TV or DSL connections) then you should also study the section on "Postfix on hosts without a real Internet hostname".
If your machine is disconnected most of the time, there isn't a lot of opportunity for Postfix to deliver mail to hard-to-reach corners of the Internet. It's better to give the mail to a machine that is connected all the time. In the example below, the [] prevents Postfix from trying to look up DNS MX records.
/etc/postfix/main.cf: relayhost = [smtprelay.someprovider.com]
Disable spontaneous SMTP mail delivery (if using on-demand dialup IP only).
Normally, Postfix attempts to deliver outbound mail at its convenience. If your machine uses on-demand dialup IP, this causes your system to place a telephone call whenever you submit new mail, and whenever Postfix retries to deliver delayed mail. To prevent such telephone calls from being placed, disable spontaneous SMTP mail deliveries.
/etc/postfix/main.cf: defer_transports = smtp (Only for on-demand dialup IP hosts)
Disable SMTP client DNS lookups (dialup LAN only).
/etc/postfix/main.cf: disable_dns_lookups = yes (Only for on-demand dialup IP hosts)
Put the following command into your PPP or SLIP dialup scripts:
/usr/sbin/sendmail -q (whenever the Internet link is up)
The exact location of the Postfix sendmail command is system-specific. Use the command "postconf sendmail_path" to find out where the Postfix sendmail command is located on your machine.
In order to find out if the mail queue is flushed, use something like:
#!/bin/sh
# Start mail deliveries.
/usr/sbin/sendmail -q
# Allow deliveries to start.
sleep 10
# Loop until all messages have been tried at least once.
while mailq | grep '^[^ ]*\*' >/dev/null
do
sleep 10
done
If you have disabled spontaneous SMTP mail delivery, you also need to run the "sendmail -q" command every now and then while the dialup link is up, so that newly-posted mail is flushed from the queue.
This section is for hosts that don't have their own Internet hostname. Typically these are systems that get a dynamic IP address via DHCP or via dialup. Postfix will let you send and receive mail just fine between accounts on a machine with a fantasy name. However, you cannot use a fantasy hostname in your email address when sending mail into the Internet, because no-one would be able to reply to your mail. In fact, more and more sites refuse mail addresses with non-existent domain names.
Note: the following information is Postfix version dependent. To find out what Postfix version you have, execute the command "postconf mail_version".
Postfix 2.2 uses the generic(5) address mapping to replace local fantasy email addresses by valid Internet addresses. This mapping happens ONLY when mail leaves the machine; not when you send mail between users on the same machine.
The following example presents additional configuration. You need to combine this with basic configuration information as discussed the first half of this document.
1 /etc/postfix/main.cf: 2 smtp_generic_maps = hash:/etc/postfix/generic 3 4 /etc/postfix/generic: 5 his@@localdomain.local hisaccount@@hisisp.example 6 her@@localdomain.local heraccount@@herisp.example 7 @@localdomain.local hisaccount+local@@hisisp.example
When mail is sent to a remote host via SMTP:
Line 5 replaces his@@localdomain.local by his ISP mail address,
Line 6 replaces her@@localdomain.local by her ISP mail address, and
Line 7 replaces other local addresses by his ISP account, with an address extension of +local (this example assumes that the ISP supports "+" style address extensions).
Specify dbm instead of hash if your system uses dbm files instead of db files. To find out what lookup tables Postfix supports, use the command "postconf -m".
Execute the command "postmap /etc/postfix/generic" whenever you change the generic table.
The solution with older Postfix systems is to use valid Internet addresses where possible, and to let Postfix map valid Internet addresses to local fantasy addresses. With this, you can send mail to the Internet and to local fantasy addresses, including mail to local fantasy addresses that don't have a valid Internet address of their own.
The following example presents additional configuration. You need to combine this with basic configuration information as discussed the first half of this document.
1 /etc/postfix/main.cf: 2 myhostname = hostname.localdomain 3 mydomain = localdomain 4 5 canonical_maps = hash:/etc/postfix/canonical 6 7 virtual_alias_maps = hash:/etc/postfix/virtual 8 9 /etc/postfix/canonical: 10 your-login-name your-account@@your-isp.com 11 12 /etc/postfix/virtual: 13 your-account@@your-isp.com your-login-name
Translation:
Lines 2-3: Substitute your fantasy hostname here. Do not use a domain name that is already in use by real organizations on the Internet. See RFC 2606 for examples of domain names that are guaranteed not to be owned by anyone.
Lines 5, 9, 10: This provides the mapping from "your-login-name@@hostname.localdomain" to "your-account@@your-isp.com". This part is required.
Lines 7, 12, 13: Deliver mail for "your-account@@your-isp.com" locally, instead of sending it to the ISP. This part is not required but is convenient.
Specify dbm instead of hash if your system uses dbm files instead of db files. To find out what lookup tables Postfix supports, use the command "postconf -m".
Execute the command "postmap /etc/postfix/canonical" whenever you change the canonical table.
Execute the command "postmap /etc/postfix/virtual" whenever you change the virtual table.

1 /etc/postfix/main.cf: 2 myorigin = $mydomain 3 mynetworks = 127.0.0.0/8 10.0.0.0/24 4 relay_domains = 5 # Optional: forward all non-local mail to mailhost 6 #relayhost = $mydomain
Translation:
Line 2: Send mail as "user@@example.com".
Line 3: Specify the trusted networks.
Line 4: This host does not relay mail from untrusted networks.
Line 6: This is needed if no direct Internet access is available. See also below, "Postfix behind a firewall".
Next we present the mailhost configuration. This machine sends mail as "user@@example.com" and is final destination for "user@@hostname.example.com" as well as "user@@example.com".
1 DNS: 2 example.com IN MX 10 mailhost.example.com. 3 4 /etc/postfix/main.cf: 5 myorigin = $mydomain 6 mydestination = $myhostname localhost.$mydomain localhost $mydomain 7 mynetworks = 127.0.0.0/8 10.0.0.0/24 8 relay_domains = 9 # Optional: forward all non-local mail to firewall 10 #relayhost = [firewall.example.com]
Translation:
Line 2: Send mail for the domain "example.com" to the machine mailhost.example.com. Remember to specify the "." at the end of the line.
Line 5: Send mail as "user@@example.com".
Line 6: This host is the final mail destination for the "example.com" domain, in addition to the names of the machine itself.
Line 7: Specify the trusted networks.
Line 8: This host does not relay mail from untrusted networks.
Line 10: This is needed only when the mailhost has to forward non-local mail via a mail server on a firewall. The [] forces Postfix to do no MX record lookups.
In an environment like this, users access their mailbox in one or more of the following ways:
Mailbox access via NFS or equivalent.
Mailbox access via POP or IMAP.
Mailbox on the user's preferred machine.
In the latter case, each user has an alias on the mailhost that forwards mail to her preferred machine:
/etc/aliases:
joe: joe@@joes.preferred.machine
jane: jane@@janes.preferred.machine
On some systems the alias database is not in /etc/aliases. To find out the location for your system, execute the command "postconf alias_maps".
Execute the command "newaliases" whenever you change the aliases file.
The idea is to set up a Postfix email firewall/gateway that forwards mail for "example.com" to an inside gateway machine but rejects mail for "anything.example.com". There is only one problem: with "relay_domains = example.com", the firewall normally also accepts mail for "anything.example.com". That would not be right.
Note: this example requires Postfix version 2.0 and later. To find out what Postfix version you have, execute the command "postconf mail_version".
The solution is presented in multiple parts. This first part gets rid of local mail delivery on the firewall, making the firewall harder to break.
1 /etc/postfix/main.cf: 2 myorigin = example.com 3 mydestination = 4 local_recipient_maps = 5 local_transport = error:local mail delivery is disabled 6 7 /etc/postfix/master.cf: 8 Comment out the local delivery agent
Translation:
Line 2: Send mail from this machine as "user@@example.com", so that no reason exists to send mail to "user@@firewall.example.com".
Lines 3-8: Disable local mail delivery on the firewall machine.
For the sake of technical correctness the firewall must be able to receive mail for postmaster@@[firewall ip address]. Reportedly, some things actually expect this ability to exist. The second part of the solution therefore adds support for postmaster@@[firewall ip address], and as a bonus we do abuse@@[firewall ip address] as well. All the mail to these two accounts is forwarded to an inside address.
1 /etc/postfix/main.cf: 2 virtual_alias_maps = hash:/etc/postfix/virtual 3 4 /etc/postfix/virtual: 5 postmaster postmaster@@example.com 6 abuse abuse@@example.com
Translation:
Because mydestination is empty (see the previous example), only address literals matching $inet_interfaces or $proxy_interfaces are deemed local. So "localpart@@[a.d.d.r]" can be matched as simply "localpart" in canonical(5) and virtual(5). This avoids the need to specify firewall IP addresses into Postfix configuration files.
The last part of the solution does the email forwarding, which is the real purpose of the firewall email function.
1 /etc/postfix/main.cf: 2 mynetworks = 127.0.0.0/8 12.34.56.0/24 3 relay_domains = example.com 4 parent_domain_matches_subdomains = 5 debug_peer_list smtpd_access_maps 6 smtpd_recipient_restrictions = 7 permit_mynetworks reject_unauth_destination 8 9 relay_recipient_maps = hash:/etc/postfix/relay_recipients 10 transport_maps = hash:/etc/postfix/transport 11 12 /etc/postfix/relay_recipients: 13 user1@@example.com x 14 user2@@example.com x 15 . . . 16 17 /etc/postfix/transport: 18 example.com smtp:[inside-gateway.example.com]
Translation:
Lines 1-7: Accept mail from local systems in $mynetworks, and accept mail from outside for "user@@example.com" but not for "user@@anything.example.com". The magic is in lines 4-5.
Lines 9, 12-14: Define the list of valid addresses in the "example.com" domain that can receive mail from the Internet. This prevents the mail queue from filling up with undeliverable MAILER-DAEMON messages. If you can't maintain a list of valid recipients then you must specify "relay_recipient_maps =" (that is, an empty value), or you must specify an "@@example.com x" wild-card in the relay_recipients table.
Lines 10, 17-18: Route mail for "example.com" to the inside gateway machine. The [] forces Postfix to do no MX lookup.
Specify dbm instead of hash if your system uses dbm files instead of db files. To find out what lookup tables Postfix supports, use the command "postconf -m".
Execute the command "postmap /etc/postfix/relay_recipients" whenever you change the relay_recipients table.
Execute the command "postmap /etc/postfix/transport" whenever you change the transport table.
In some installations, there may be separate instances of Postfix processing inbound and outbound mail on a multi-homed firewall. The inbound Postfix instance has an SMTP server listening on the external firewall interface, and the outbound Postfix instance has an SMTP server listening on the internal interface. In such a configuration is it is tempting to configure $inet_interfaces in each instance with just the corresponding interface address.
In most cases, using inet_interfaces in this way will not work, because as documented in the $inet_interfaces reference manual, the smtp(8) delivery agent will also use the specified interface address as the source address for outbound connections and will be unable to reach hosts on "the other side" of the firewall. The symptoms are that the firewall is unable to connect to hosts that are in fact up. See the inet_interfaces parameter documentation for suggested work-arounds.
A drawback of sending mail as "user@@example.com" (instead of "user@@hostname.example.com") is that mail for "root" and other system accounts is also sent to the central mailhost. In order to deliver such accounts locally, you can set up virtual aliases as follows:
1 /etc/postfix/main.cf: 2 virtual_alias_maps = hash:/etc/postfix/virtual 3 4 /etc/postfix/virtual: 5 root root@@localhost 6 . . .
Translation:
Line 5: As described in the virtual(5) manual page, the bare name "root" matches "root@@site" when "site" is equal to $myorigin, when "site" is listed in $mydestination, or when it matches $inet_interfaces or $proxy_interfaces.
The simplest way to set up Postfix on a host behind a firewalled network is to send all mail to a gateway host, and to let that mail host take care of internal and external forwarding. Examples of that are shown in the local area network section above. A more sophisticated approach is to send only external mail to the gateway host, and to send intranet mail directly. That's what Wietse does at work.
Note: this example requires Postfix version 2.0 and later. To find out what Postfix version you have, execute the command "postconf mail_version".
The following example presents additional configuration. You need to combine this with basic configuration information as discussed the first half of this document.
1 /etc/postfix/main.cf: 2 transport_maps = hash:/etc/postfix/transport 3 relayhost = 4 # Optional for a machine that isn't "always on" 5 #fallback_relay = [gateway.example.com] 6 7 /etc/postfix/transport: 8 # Internal delivery. 9 example.com : 10 .example.com : 11 # External delivery. 12 * smtp:[gateway.example.com]
Translation:
Lines 2, 7-12: Request that intranet mail is delivered directly, and that external mail is given to a gateway. Obviously, this example assumes that the organization uses DNS MX records internally. The [] forces Postfix to do no MX lookup.
Line 5: This prevents mail from being stuck in the queue when the machine is turned off. Postfix tries to deliver mail directly, and gives undeliverable mail to a gateway.
Specify dbm instead of hash if your system uses dbm files instead of db files. To find out what lookup tables Postfix supports, use the command "postconf -m".
Execute the command "postmap /etc/postfix/transport" whenever you edit the transport table.
This section presents additional configuration. You need to combine this with basic configuration information as discussed the first half of this document.
When your system is SECONDARY MX host for a remote site this is all you need:
1 DNS: 2 the.backed-up.domain.tld IN MX 100 your.machine.tld. 3 4 /etc/postfix/main.cf: 5 relay_domains = . . . the.backed-up.domain.tld 6 smtpd_recipient_restrictions = 7 permit_mynetworks reject_unauth_destination 8 9 # You must specify your NAT/proxy external address. 10 #proxy_interfaces = 1.2.3.4 11 12 relay_recipient_maps = hash:/etc/postfix/relay_recipients 13 14 /etc/postfix/relay_recipients: 15 user1@@the.backed-up.domain.tld x 16 user2@@the.backed-up.domain.tld x 17 . . .
When your system is PRIMARY MX host for a remote site you need the above, plus:
18 /etc/postfix/main.cf: 19 transport_maps = hash:/etc/postfix/transport 20 21 /etc/postfix/transport: 22 the.backed-up.domain.tld relay:[their.mail.host.tld]
Important notes:
Do not list the.backed-up.domain.tld in mydestination.
Do not list the.backed-up.domain.tld in virtual_alias_domains.
Do not list the.backed-up.domain.tld in virtual_mailbox_domains.
Lines 1-7: Forward mail from the Internet for "the.backed-up.domain.tld" to the primary MX host for that domain.
Line 10: This is a must if Postfix receives mail via a NAT relay or proxy that presents a different IP address to the world than the local machine.
Lines 12-16: Define the list of valid addresses in the "the.backed-up.domain.tld" domain. This prevents your mail queue from filling up with undeliverable MAILER-DAEMON messages. If you can't maintain a list of valid recipients then you must specify "relay_recipient_maps =" (that is, an empty value), or you must specify an "@@the.backed-up.domain.tld x" wild-card in the relay_recipients table.
Line 22: The [] forces Postfix to do no MX lookup.
Specify dbm instead of hash if your system uses dbm files instead of db files. To find out what lookup tables Postfix supports, use the command "postconf -m".
Execute the command "postmap /etc/postfix/transport" whenever you change the transport table.
NOTE for Postfix < 2.2: Do not use the fallback_relay feature when relaying mail for a backup or primary MX domain. Mail would loop between the Postfix MX host and the fallback_relay host when the final destination is unavailable.
These are default settings in Postfix version 2.2 and later.
This section applies to dialup connections that are down most of the time. For dialup connections that are up 24x7, see the local area network section above.
This section presents additional configuration. You need to combine this with basic configuration information as discussed the first half of this document.
If you do not have your own hostname and IP address (usually with dialup, cable TV or DSL connections) then you should also study the section on "Postfix on hosts without a real Internet hostname".
If your machine is disconnected most of the time, there isn't a lot of opportunity for Postfix to deliver mail to hard-to-reach corners of the Internet. It's better to give the mail to a machine that is connected all the time. In the example below, the [] prevents Postfix from trying to look up DNS MX records.
/etc/postfix/main.cf: relayhost = [smtprelay.someprovider.com]
Disable spontaneous SMTP mail delivery (if using on-demand dialup IP only).
Normally, Postfix attempts to deliver outbound mail at its convenience. If your machine uses on-demand dialup IP, this causes your system to place a telephone call whenever you submit new mail, and whenever Postfix retries to deliver delayed mail. To prevent such telephone calls from being placed, disable spontaneous SMTP mail deliveries.
/etc/postfix/main.cf: defer_transports = smtp (Only for on-demand dialup IP hosts)
Disable SMTP client DNS lookups (dialup LAN only).
/etc/postfix/main.cf: disable_dns_lookups = yes (Only for on-demand dialup IP hosts)
Put the following command into your PPP or SLIP dialup scripts:
/usr/sbin/sendmail -q (whenever the Internet link is up)
The exact location of the Postfix sendmail command is system-specific. Use the command "postconf sendmail_path" to find out where the Postfix sendmail command is located on your machine.
In order to find out if the mail queue is flushed, use something like:
#!/bin/sh
# Start mail deliveries.
/usr/sbin/sendmail -q
# Allow deliveries to start.
sleep 10
# Loop until all messages have been tried at least once.
while mailq | grep '^[^ ]*\*' >/dev/null
do
sleep 10
done
If you have disabled spontaneous SMTP mail delivery, you also need to run the "sendmail -q" command every now and then while the dialup link is up, so that newly-posted mail is flushed from the queue.
This section is for hosts that don't have their own Internet hostname. Typically these are systems that get a dynamic IP address via DHCP or via dialup. Postfix will let you send and receive mail just fine between accounts on a machine with a fantasy name. However, you cannot use a fantasy hostname in your email address when sending mail into the Internet, because no-one would be able to reply to your mail. In fact, more and more sites refuse mail addresses with non-existent domain names.
Note: the following information is Postfix version dependent. To find out what Postfix version you have, execute the command "postconf mail_version".
Postfix 2.2 uses the generic(5) address mapping to replace local fantasy email addresses by valid Internet addresses. This mapping happens ONLY when mail leaves the machine; not when you send mail between users on the same machine.
The following example presents additional configuration. You need to combine this with basic configuration information as discussed the first half of this document.
1 /etc/postfix/main.cf: 2 smtp_generic_maps = hash:/etc/postfix/generic 3 4 /etc/postfix/generic: 5 his@@localdomain.local hisaccount@@hisisp.example 6 her@@localdomain.local heraccount@@herisp.example 7 @@localdomain.local hisaccount+local@@hisisp.example
When mail is sent to a remote host via SMTP:
Line 5 replaces his@@localdomain.local by his ISP mail address,
Line 6 replaces her@@localdomain.local by her ISP mail address, and
Line 7 replaces other local addresses by his ISP account, with an address extension of +local (this example assumes that the ISP supports "+" style address extensions).
Specify dbm instead of hash if your system uses dbm files instead of db files. To find out what lookup tables Postfix supports, use the command "postconf -m".
Execute the command "postmap /etc/postfix/generic" whenever you change the generic table.
The solution with older Postfix systems is to use valid Internet addresses where possible, and to let Postfix map valid Internet addresses to local fantasy addresses. With this, you can send mail to the Internet and to local fantasy addresses, including mail to local fantasy addresses that don't have a valid Internet address of their own.
The following example presents additional configuration. You need to combine this with basic configuration information as discussed the first half of this document.
1 /etc/postfix/main.cf: 2 myhostname = hostname.localdomain 3 mydomain = localdomain 4 5 canonical_maps = hash:/etc/postfix/canonical 6 7 virtual_alias_maps = hash:/etc/postfix/virtual 8 9 /etc/postfix/canonical: 10 your-login-name your-account@@your-isp.com 11 12 /etc/postfix/virtual: 13 your-account@@your-isp.com your-login-name
Translation:
Lines 2-3: Substitute your fantasy hostname here. Do not use a domain name that is already in use by real organizations on the Internet. See RFC 2606 for examples of domain names that are guaranteed not to be owned by anyone.
Lines 5, 9, 10: This provides the mapping from "your-login-name@@hostname.localdomain" to "your-account@@your-isp.com". This part is required.
Lines 7, 12, 13: Deliver mail for "your-account@@your-isp.com" locally, instead of sending it to the ISP. This part is not required but is convenient.
Specify dbm instead of hash if your system uses dbm files instead of db files. To find out what lookup tables Postfix supports, use the command "postconf -m".
Execute the command "postmap /etc/postfix/canonical" whenever you change the canonical table.
Execute the command "postmap /etc/postfix/virtual" whenever you change the virtual table.
@ 1.1.1.1.2.3 log @Pull up following revision(s) (requested by tron in ticket #1425): Update Postfix to version 2.7.1: - Improved before-queue content filter performance. With "smtpd_proxy_options = speed_adjust", the Postfix SMTP server receives the entire message before it connects to a before-queue content filter. Typically, this allows Postfix to handle the same mail load with fewer content filter processes. - Improved address verification performance. The verify database is now persistent by default, and it is automatically cleaned periodically. Under overload conditions, the Postfix SMTP server no longer waits up to 6 seconds for an address probe to complete. - Support for reputation management based on the local SMTP client IP address. This is typically implemented with "FILTER transportname:" actions in access maps or header/body checks, and mail delivery transports in master.cf with unique smtp_bind_address values. @ text @d322 1 a322 1 4 /etc/postfix/virtual: d428 1 a428 1 4 /etc/postfix/virtual: a444 3Execute the command "postmap /etc/postfix/virtual" after editing the file.
