Postfix 2.4.6 / 2.3.13 / 2.2.12

Het programma Postfix is een opensource mta, ook wel mailserver genoemd, voor Unix- en Linux-systemen. Postfix werd oorspronkelijk ontwikkeld als een snelle en eenvoudiger te beheren tegenhanger van sendmail. Voor meer informatie verwijzen we jullie door naar deze pagina bomvol met handleidingen en documentatie. Wietse Venema heeft drie nieuwe versies uitgebracht met 2.4.6, 2.3.13 en 2.2.12 als de versienummers. De aankondiging op de mailinglijst ziet er als volgt uit:

Postix official release 2.4.6, 2.3.13, 2.2.12 available.

Postfix stable release 2.4.6 etc. fix minor problems in the SMTP client, and work around "noatime" mail queues. Note: stable releases do not change except for bugfixes and emergencies. New features are introduced via the experimental release (currently, Postfix 2.5).

• A remote SMTP client TLS certificate with an unparsable canonical name triggered a panic error in the Postfix SMTP server (attempt to allocate zero-length memory) while sending a request to an SMTPD policy server.
• On backup MX servers where the queue file system is mounted with "atime" (file read/execute access time) updates disabled, the flush daemon would trigger mail delivery attempts once every 1000 seconds, thus rendering the maximal_backoff_time setting useless for backup MX service.

With Postfix 2.2.12, the following erratum was fixed, back-ported from Postfix 2.3:

• With remote SMTP server tarpit delays larger than smtp_rset_timeout, the Postfix SMTP client could get out of sync with the remote SMTP server while reusing a connection. The symptoms were "recipient rejected .. in reply to DATA".

Available from the mirrors listed here.

A patch for stress-adaptive behavior, making Postfix more responsive when all its SMTP server ports are busy, will be made available separately. This feature is currently built into Postfix only with the experimental (2.5) release.
