All releases tagged Bugfixes
Release Notes: The trace client was made asynchronous, since a high load of DSN success notification requests could slow down the queue manager. The local(8) delivery agent ignored certain table lookup errors. dbl.spamhaus.org rejects lookups with "No IP queries" even if the name has an alphanumerical prefix, so these lookups are now skipped. The "sendmail -t" command reported "protocol error" instead of "file too large", "no space left on device", etc. The Postfix Milter client reported a temporary error instead of "file too large" in three cases. Also, Linux kernel version 3 support has been added.
Release Notes: This version contains a fix for CVE-2011-1720, which affects Postfix SMTP server configurations that use Cyrus SASL authentication. This defect was introduced with the Postfix SASL patch, and is present in all Postfix versions where the command "postconf mail_release_date" reports a value of 20000314 (March 14, 2000) or greater. Note that CVE-2011-1720 does not affect Postfix SMTP servers that use Dovecot SASL authentication. It also does not affect the common Postfix SMTP server configurations that use only Cyrus SASL mechanisms PLAIN and LOGIN.
Release Notes: When a client disconnected and then reconnected before all DNSBL results for the earlier session arrived, DNSBL results for the earlier session would be added to the score for the later session. The SMTP client did not support mail to [ipv6:ipv6addr]. FreeBSD closefrom() was back-ported to FreeBSD 7, breaking FreeBSD 7.x support retroactively. The SUN compiler had trouble with a pointer expression of the form "("text1" "text2") + constant''.
Release Notes: This release fixes one "signal 11" bug with SMTP server debug logging, and cleans up some code and documentation.
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).
