Download Postfix 2.4.3 / 2.3.11

The Postfix program is an open source mta, also called a mail server, for Unix and Linux systems. Postfix was originally developed as a fast and easier to manage counterpart to sendmail. For more information, we refer you to this page packed with manuals and documentation. Wietse Venema has released two new versions with 2.4.3 and 2.3.11 as the version numbers. The announcement on the mailing list looks like this:

Postfix stable releases 2.4.3 and 2.3.11 are available. Except for emergencies these will be the last stable releases in a while. Postfix 2.4.2 and 2.3.10 were released yesterday, but these did not compile on all the supported platforms. It did not seem right if some people would have to wait several months for an update.

• Bugfix: don’t falsely report “lost connection from localhost[127.0.0.1]” when Postfix is ​​being portscanned. Files: smtpd/smtpd_peer.c, qmqpd/qmqpd_peer.c.
• Robustness: recommend a “0” process limit for policy servers to avoid “connection refused” problems when the smtpd process limit exceeds the default process limit. File: proto/SMTPD_POLICY_README.html.
• Safety: when IPv6 (or IPv4) is turned off, don’t treat an IPv6 (or IPv4) connection from eg inetd as if it comes from localhost[127.0.0.1]. Files: smtpd/smtpd_peer.c, qmqpd/qmqpd_peer.c.
• Bugfix: Content-Transfer-Encoding: attribute values ​​are case insensitive. File: src/cleanup/cleanup_message.c.
• Bugfix: mailbox_transport(_maps) and fallback_transport(_maps) were broken when used with the error(8) or discard(8) transports. Cause: insufficient documentation. Files: error/error.c, discard/discard.c.
• Bugfix (problem introduced Postfix 2.3): when DSN support was introduced it broke “agressive” recipient duplicate elimination with “enable_original_recipient = no”. File: cleanup/cleanup_out_recipient.c.
• Bugfix (introduced Postfix 2.3): the sendmail/postdrop commands would hang when trying to submit a message larger than the per-message size limit. File: postdrop/postdrop.c.
• Sabotage the saboteur who insists on breaking Postfix by adding gethostbyname() calls that cause maildir delivery to fail when the machine name is not found in /etc/hosts, or that cause Postfix processes to hang when the network is down.
• Portability: Victor helpfully pointed out that change 20070425 broke on non-IPv6 systems. Files: smtpd/smtpd_peer.c, qmqpd/qmqpd_peer.c.
