Log message:
Update postfix to 2.11.6, security release.

With all supported Postfix releases, the default settings have been
updated so that they no longer enable export-grade ciphers, and no
longer enable the SSLv2 and SSLv3 protocols. These ciphers and
protocols have little if any legitimate use today, and have instead
become a vehicle for downgrade attacks. There are no other code
changes.

Postfix documentation has been updated to reflect the new default
settings and their rationale; the RELEASE_NOTES give suggestions
for how to enable the old ciphers and protocols if your infrastructure
requires them.

Finally, abandoning deprecated ciphers and protocols does not really
improve TLS security without measures to better authenticate remote
servers. Secure DNS and TLSA are steps in that direction.

Log message:
Recursive PKGREVISION bump for all packages mentioning 'perl',
having a PKGNAME of p5-*, or depending such a package,
for perl-5.22.0.

Log message:
Update postfix to 2.11.5.

Fixed in Postfix 3.0 and 2.11:

  * Preparation for OpenSSL 1.2 API changes.

Fixed in all supported releases:

  * The sender_dependent_relayhost_maps feature ignored the relayhost
    setting in the case of a DUNNO lookup result. It would use the
    recipient domain instead.

Log message:
Move Berkeley DB compilation definition from options.mk to Makefile
and remove "bdb" option.

Because Berkeley DB is always mandatory, it does not make sense to
force users to enable "bdb" option to use Berkeley DB.

Log message:
Revbump after updating textproc/icu

Log message:
Fix build break when pgsql enabled on Mac OS X 10.10.

Log message:
Update postfix to 2.11.4.

Postfix 2.11.4 only:

* Fix a core dump when smtp_policy_maps specifies an invalid TLS
  level.

* Fix a missing " in \%s\", in postconf(1) fatal error messages,
  which violated the C language spec. Reported by Iain Hibbert.

All supported releases:

* Stop excessive recursion in the cleanup server while recovering
  from a virtual alias expansion loop. Problem found at Two Sigma.

* Stop exponential memory allocation with virtual alias expansion
  loops. This came to light after fixing the previous problem.

Log message:
Update postfix to 2.11.3.

Bugfix for Postfix 2.11, 2.10, 2.9 and 2.8:

  * Fix for configurations that prepend message headers with Postfix
    access maps, policy servers or Milter applications. Postfix now
    hides its own Received: header from Milters and exposes prepended
    headers to Milters, regardless of the mechanism used to prepend
    a header. This fix reverts a partial solution that was released
    on October 13, 2014, and replaces it with a complete solution.

Portability fix for Postfix 2.11:

  * Portability fix for MacOS X 10.7.x (Darwin 11.x) build procedure.

Log message:
Update postfix to 2.11.2.

Bugfixes for Postfix 2.11, 2.10, 2.9 and 2.8:

  * Fix for DMARC implementations based on SPF policy plus DKIM
    Milter. The PREPEND access/policy action added headers ABOVE
    Postfix's own Received: header, exposing Postfix's own Received:
    header to Milters (protocol violation) and hiding the PREPENDed
    header from Milters. PREPENDed headers are now added BELOW
    Postfix's own Received: header and remain visible to Milters.

  * The Postfix SMTP server logged an incorrect client name in
    reject messages for check_reverse_client_hostname_access and
    check_reverse_client_hostname_{mx,ns}_access. They replied with
    the verified client name, instead of the name that was rejected.

  * The qmqpd daemon crashed with null pointer bug when logging a
    lost connection while not in a mail transaction.
