Smail

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.

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.

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.

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.

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.
