- Update to 3.4.4
  o Incompatible changes
    - The Postfix SMTP server announces CHUNKING (BDAT
      command) by default. In the unlikely case that this breaks some
      important remote SMTP client, disable the feature as follows:
      
      /etc/postfix/main.cf:
          # The logging alternative:
          smtpd_discard_ehlo_keywords = chunking
          # The non-logging alternative:
          smtpd_discard_ehlo_keywords = chunking, silent_discard
    - This introduces a new master.cf service 'postlog'
      with type 'unix-dgram' that is used by the new postlogd(8) daemon.
      Before backing out to an older Postfix version, edit the master.cf
      file and remove the postlog entry.
    - Postfix 3.4 drops support for OpenSSL 1.0.1
    - To avoid performance loss under load, the
      tlsproxy(8) daemon now requires a zero process limit in master.cf
      (this setting is provided with the default master.cf file). By
      default, a tlsproxy(8) process will retire after several hours.
    - To set the tlsproxy process limit to zero:
      postconf -F tlsproxy/unix/process_limit=0
      postfix reload
  o Major changes 
    - Postfix SMTP server support for RFC 3030 CHUNKING
      (the BDAT command) without BINARYMIME, in both smtpd(8) and
      postscreen(8). This has no effect on Milters, smtpd_mumble_restrictions,
      and smtpd_proxy_filter. See BDAT_README for more.
    - Support for logging to file or stdout, instead of using syslog.
    - Logging to file solves a usability problem for MacOS, and

o Major changes
- Postfix SMTP server support for RFC 3030 CHUNKING
(the BDAT command) without BINARYMIME, in both smtpd(8) and
postscreen(8). This has no effect on Milters, smtpd_mumble_restrictions,
and smtpd_proxy_filter. See BDAT_README for more.
- Support for logging to file or stdout, instead of using syslog.
- Logging to file solves a usability problem for MacOS, and
eliminates multiple problems with systemd-based systems.
- Logging to stdout is useful when Postfix runs in a container, as
it eliminates a syslogd dependency.
- Better handling of undocumented(!) Linux behavior
whether or not signals are delivered to a PID=1 process.
- Support for (key, list of filenames) in map source text.
Currently, this feature is used only by tls_server_sni_maps.
- Automatic retirement: dnsblog(8) and tlsproxy(8) process
will now voluntarily retire after after max_idle*max_use, or some
sane limit if either limit is disabled. Without this, a process
could stay busy for days or more.
- Postfix SMTP client support for multiple deliveries
per TLS-encrypted connection. This is primarily to improve mail
delivery performance for destinations that throttle clients when
they don't combine deliveries.
This feature is enabled with "smtp_tls_connection_reuse=yes" in
main.cf, or with "tls_connection_reuse=yes" in smtp_tls_policy_maps.
It supports all Postfix TLS security levels including dane and
dane-only.
- SNI support in the Postfix SMTP server, the
Postfix SMTP client, and in the tlsproxy(8) daemon (both server and
client roles). See the postconf(5) documentation for the new
tls_server_sni_maps and smtp_tls_servername parameters.
- Support for files that contain multiple (key, certificate, trust chain)
instances. This was required to implement
server-side SNI table lookups, but it also eliminates the need for
separate cert/key files for RSA, DSA, Elliptic Curve, and so on.
- Support for smtpd_reject_footer_maps (as well as the postscreen
variant postscreen_reject_footer_maps) for more informative reject
messages. This is indexed with the Postfix SMTP server response
text, and overrides the footer specified with smtpd_reject_footer.
One will want to use a pcre: or regexp: map with this.
o Bugfixes
- Andreas Schulze discovered that reject_multi_recipient_bounce
was producing false rejects with BDAT commands. This problem
already existed with Postfix 2.2 smtpd_end_of_data_restrictons.
Postfix 3.4.4 fixes both.
