Postfix legacy release 2.7.8, 2.6.14 and 2.5.17

[An on-line version of this announcement will be available at]

Postfix legacy releases 2.7.8, 2.6.14 and 2.5.17 are available.
This is the final update for Postfix 2.5, released in 2008. From
now on, the supported stable and legacy releases are Postfix 2.6
.. 2.9. New features appear in the Postfix 2.10 development release.

    * (Postfix 2.5, 2.6) While the Postfix SMTP client's protocol
      parser uses the last SMTP reply line as intended, the error
      processing routine was taking information from the beginning
      of the response. This was causing "Protocol error" bounces
      with postscreen multi-line responses and Postfix <= 2.6 clients.

    * (Postfix 2.5, 2.6, 2.7) The fix for local delivery agent
      database lookup errors was incomplete. The fix correctly added
      new code to detect database lookup errors with
      mailbox_transport_maps, mailbox_command_maps or
      fallback_transport_maps, but it failed to log the problem,
      and to produce a defer logfile record which is needed for
      "delayed mail" and "mail too old" delivery status notifications.

    * (Postfix 2.5, 2.6, 2.7) The trace(8) service, used for DSN
      SUCCESS notifications, did not distinguish between notifications
      for a non-bounce or a bounce message, causing it to "reply"
      to mail with the null sender address. Problem reported by
      Sabahattin Gucukoglu.

    * (Postfix 2.5, 2.6, 2.7) The "change header" milter request
      could replace the wrong header. A long header name could match
      a shorter one, because a length check was done on the wrong
      string. Reported by Vladimir Vassiliev.

    * (Postfix 2.7) Support for Dovecot auth over TCP sockets, using
      code that already existed for testing purposes.
