Release Notes: This release fixes minor problems in the SMTP client, and works around "noatime" mail queues.
Release Notes: This release contains back-ported fixes from Postfix 2.3. The PostgreSQL client was updated after major database API changes in response to PostgreSQL security issues. The Postfix SMTP client enforced Mandatory TLS only when talking to an ESMTP server.
Release Notes: "sendmail -t" did not remove the CR from lines ending in CRLF. A workaround was made for fatal errors in PCRE maps when an expression in () matches empty text (since the PCRE library returns an inappropriate error code). Fixes were made for non-security bugs that were found in code that handles impossible error conditions.
Release Notes: This release consists mostly of a collection of back-ported fixes from the Postfix 2.3 development branch. Most of this patch hardens the TLS implementation against DNS-based attacks, and eliminates some anomalies from the TLS per-site policy engine. It also adds a workaround that prevents Postfix from repeatedly trying to deliver mail to domains with a malformed MX record (for example, with a null MX hostname). It bounces such mail immediately.
Release Notes: This release backed out of a workaround for broken servers and firewalls that created more problems than it solved.
Release Notes: This release catches up with minor fixes that were fielded earlier in the experimental Postfix 2.3 snapshots.
Release Notes: This release addresses some portability problems with LP64 platforms that broke SMTP connection caching. SMTP connection caching is now more failure tolerant. These fixes are back-ported from the experimental (2.3) release series.
Release Notes: This release addresses a bunch of minor issues that emerged during deployment and during code reviews while developing Postfix 2.3.
Release Notes: This release fixes minor problems that were found in Postfix 2.2 during deployment, or in Postfix 2.3 during development. These include fixes for a SASL interoperability problem causing Sendmail servers to hang up on Postfix, as well as a panic when a fall-back relay could not be used for a variety of reasons.
Release Notes: This release features a more usable REPLACE action in header/body_checks, portability to HP-UX, and fixes for two harmless defects in the SMTP and LMTP clients that go back to before the first Postfix release.
