Release Notes: This is a major update fixing reported security problems and fixing may other bugs big and small.
Release Notes: This release deals solely with a problem in a minor change in the previous release which unexpectedly resulted in sender addresses being truncated to just their mailbox part.
Release Notes: This release is primarily a bugfix and clean-up release. It also includes a first cut at message arrival and delivery delay accounting. This release further adapts the makefiles to be portable between all major variants of make in use on modern systems while at the same time still supporting useful developer and maintainer features such as automated dependency tracking.
Release Notes: This release fixes a major botch that was made in the host domain name RE parsing and matching code. The checkerr utility script now automatically recognizes and registers all non-local double-bounce original senders in the dead-mail.senders database so that future messages from these addresses will not accumulate in the error queue.
Release Notes: This is a minor bugfix and minor release update. Handling of regular expressions for host domain name lists is now more consistent, and their associated messages may now make use of sub-string substitution in the same way as in content filters. Duplicate HELO reject records are suppressed from the log file. The log analysis utility has been further improved. Networks and hosts that are clients only and that should not send fake bounces can now be specified.
Release Notes: This release cleans up many issues with the previous one and adds a few new features, the most important of which are regular expression (PCRE)-based content filters for both message headers and the message body. There is a new "error" director driver which gives the postmaster control over the error message text for specific rejected addresses. The "pipe" transport now has far more control and flexibility over how it handles abnormal conditions, allowing it to correctly handle temporary errors from the likes of the Cyrus IMAP daemon. Bounce messages are now much more readable.
Release Notes: There have been a great many significant changes since 188.8.131.52. Some of the most significant involve new access control features and much better security against DNS spoofing. One of the more fun new features is a handy little AWK script for reporting interesting statistics from your logfile.
Release Notes: Bounce messages were getting lost, and more than 2GB of free spool space was causing an integer overflow.
Release Notes: Bugfixes, a better tar-pit, RHSBL support, better portability, better support for the error queue, and more robust reservation of free disk space.
Release Notes: Optional use of TCP Wrappers has been eliminated and all its features have been directly integrated. There are also a number of improvements to the SMTP transport.
