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 comes with minor fixes and typo corrections that introduce no change in documented behavior.
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.
Release Notes: This release solves four portability problems that surfaced in the week since the 2.2.0 release, one harmless bug in the TLS session cache cleaning code, and minor documentation problems that were reported on the Postfix list and in private email.
Release Notes: The official Postfix 2.2 release adopts widely used third-party patches and a bunch of new functionality that was developed over the past year.
Release Notes: This snapshot is the first production release with IPv6 support. In order to accommodate both IPv4 and IPv6 support, some low-level networking code had to be restructured. After extensive testing and cleanup, the code should now be safe to use. This snapshot does not include TLS support.
Release Notes: This snapshot is expected to be the last one before STARTTLS support is merged into the main source tree. The NIS+ client by Geoff Gibbs is now part of the Postfix source tree. By default, Postfix no longer appends its own domain to addresses in message headers from remote clients. Thus, spam from poorly written software no longer looks like it came from a local user. Postfix either does not rewrite remote message headers at all, or it rewrites headers and appends the domain name that is specified with the remote_header_rewrite_domain parameter.
Release Notes: This release adds per SMTP client message rate and recipient rate limits. These limit the number of MAIL FROM or RCPT TO requests per time unit, regardless of whether or not Postfix would have accepted them otherwise. Additionally, SASL authentication attributes are now stored queue files and are passed on to delivery agents. The first delivery agent to take advantage of this is the pipe(8) delivery agent.
