Release Notes: A high load of DSN success notification requests could slow down the queue manager, which is now worked around by making the trace client asynchronous, just like the bounce and defer clients. The local delivery agent ignored table lookup errors in mailbox_command_maps, mailbox_transport_maps, fallback_transport_maps, and alias owner lookup, which is now fixed. Both RHSBL and RHSWL queries for names ending in a numerical suffix are now skipped. The Postfix Milter client reported a temporary error instead of "file too large" in three cases. Linux kernel version 3 support has been added.
Release Notes: This release contains a fix for CVE-2011-0411, which allows plain text command injection with SMTP sessions over TLS. This defect was introduced with Postfix version 2.2. The same flaw exists in other implementations of the STARTTLS command.
Release Notes: Postfix no longer automatically appends the system default CA certificates. When pipe-to-command delivery fails with a signal, mail is now correctly deferred, instead of being returned to sender. Poor `smtpd_proxy_filter` TCP performance over loopback (127.0.0.1) connections was fixed by adapting the output buffer size to the MTU. The SMTP server no longer applies the `reject_rhsbl_helo` feature to non-domain forms such as network addresses. The Postfix SMTP server failed to deliver a "421" response and hang up the connection after Milter error.
Release Notes: A problem where the Postfix SMTP client did not skip "unknown" SMTP client attributes, causing a syntax error when sending an "unknown" client PORT attribute was fixed. Postfix will now skip LDAP queries with non-ASCII search strings, instead of failing with a database lookup error. A warning is now logged when a matchlist has a #comment at the end of a line (for example mynetworks or relay_domains).
Release Notes: The before-queue content filter performance and address verification performance have been improved. Support for reputation management based on the local SMTP client IP address has been added.
