Release Notes for mailprocd 1.2 (Damnable Dominion) --------------------------------------------------- Here are some of the notable changes since mailprocd 1.1 in no particular order. For a complete list of all changes, see ChangeLog-1.2.txt. - Implement queueing; use a set of per-user "worker" processes to perform all delivery. This provides fairness, prevents heavy spam-filtering users from causing excessive load and even allows mailprocd to be used as a standalone MTA. - Added support for SMTP connection caching. - Added support for LMTP over a unix socket. - Unix sockets used by spamcheck processes are now contained in per-user directories, so control-socket requests are no longer required for unlinking them. - Fix potential crash bug if a rules.db entry was missing maxsize. - The SMTP server now conforms to RFC2034 and RFC1854. - Fix a bug in the SMTP server that would cause unnecessary retransmissions. - Added "mailmond" utility, a mail delivery delay monitor. - Complete signal-safety audit; fixed some potential signal-related issues. - Log any SIGPIPE caused by user filters not properly reading their input, so we can notify users about them. - Nicer handling of out of memory conditions.
