Summary:

Postfix 3.9 (July 2022): This release focused on enhancing the TLS
(Transport Layer Security) capabilities of Postfix. It introduced
support for TLSv1.3, allowing for more secure and efficient encrypted
communications. Additionally, improvements were made to the handling
of TLSA records, which are used in DNS-based Authentication of
Named Entities (DANE) to associate TLS certificates with domain
names.

Postfix 3.10 (July 2023): This version brought significant updates
to Postfix's SMTP (Simple Mail Transfer Protocol) functionalities.
It added support for the SMTPUTF8 extension, enabling the use of
UTF-8 encoding in email addresses and headers, which is essential
for internationalization. The release also included performance
optimizations, particularly in the handling of large mail queues,
and introduced new configuration parameters to provide administrators
with finer control over mail processing.

The changes are described more in detail in:
3.10 changes: RELEASE_NOTES
3.9 changes: RELEASE_NOTES_3.9
3.8 changes: RELEASE_NOTES_3.8
 1.1.1.2  14-Feb-2017  christos The stable Postfix release is called postfix-3.0.x where 3=major
release number, 0=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-3.1-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 2.10 or earlier, read RELEASE_NOTES-2.11
before proceeding.

 1.1.1.1.2.3  07-Jan-2011  riz Apply patch (requested by tron in ticket #1501):

Update Postfix to version 2.7.2:
- Postfix no longer automatically appends the system default CA
(certificate authority) certificates, when it reads the CA
certificates specified with {smtp, lmtp, smtpd}_tls_CAfile or
with {smtp, lmtp, smtpd}_tls_CApath. This prevents third-party
certificates from getting mail relay permission with the
permit_tls_all_clientcerts feature. Unfortunately, this change
may cause compatibility problems with configurations that rely
on certificate verification for other purposes. To get the old
behavior, specify "tls_append_default_CA = yes".
- A prior fix for compatibility with Postfix < 2.3 was incomplete.
When pipe-to-command delivery fails with a signal, mail is now
correctly deferred, instead of being returned to sender.
- Poor smtpd_proxy_filter TCP performance over loopback (127.0.0.1)
connections was fixed by adapting the output buffer size to the
MTU.
- The SMTP server no longer applies the reject_rhsbl_helo feature
to non-domain forms such as network addresses. This would cause
false positives with dbl.spamhaus.org.
- The Postfix SMTP server failed to deliver a "421" response and
hang up the connection after Milter error. Instead, the server
delivered a "503 Access denied" response and left the connection
open, due to some Postfix 1.1 workaround for RFC 2821.
- The milter_header_checks parser failed to enable any of the actions
that have no effect on message delivery (warn, replace, prepend,
ignore, dunno, and ok).
