Postfix stable release 3.4.5 and legacy releases 3.3.4, 3.2.9, 3.1.12

Wietse Venema
[An on-line version of this announcement will be available at
http://www.postfix.org/announcements/postfix-3.4.5.html]

This update fixes 5+ year old bugs, and provides a Postfix 3.4 fix
for sites that depend on undocumented behavior.

Changes for all supported stable releases:

  * Starting with Postfix 3.0, LMTP connections over UNIX-domain
    sockets were cached but not reused. Therefore, idle cached
    connections could exhaust LMTP server resources, resulting in
    two-second pauses between email deliveries. Problem reported
    by Juliana Rodrigueiro.

Changes for Postfix 3.4:

  * With message_size_limit=0, which is NOT SUPPORTED by any
    documentation, BDAT chunks were always rejected as too large.

Changes for Postfix 3.3, 3.2, 3.1, already part of Postfix 3.4:

  * Starting with Postfix 2.2, reject_multi_recipient_bounce produced
    false rejects with smtpd_end_of_data_restrictons. The same bug
    was causing false rejects with the Postfix 3.4 BDAT command.
    The latter was reported by Andreas Schulze.
