Before proceeding, you should check the release notes for your PowerMail version, as specified in the name of the distribution file.
Polished open source release, with help from the community. Large amount of changes and very important bugfixes. Bugs fixed:
Oops - all threads share one common current working directory, pplistener assumed each instance would have its own. Upgrade yesterday. This could probably not lead to miss delivered email but perhaps to failed deliveries however.
SMTP remotes can now give an unadorned HELO (Marcello Scacchetti)
pplistener did not honor the config-dir setting.
SMTP banner had ESMTP in the wrong place.
Non-existing addresses now result in the proper error code (Marcello Scacchetti)
Compiling the 'textbase' userbase accidentally required MySQL include files (spotted by Stef van Dessel)
Makefile now honors directory ./configuration directives (spotted by Florus Both)
Unnecessary use of -lmysqlclient_r instead of -lmysqlclient (spotted by Florus Both)
Potential crashes due to use of gethostbyname instead of gethostbyname_r (spotted by Stef van Dessel)
Generic LDAP support. The aim is to get PowerMail to understand the vast majority of LDAP layouts people use. This version can probably connect to 'most', please let us know if you can't fit PowerMail to your schema, and we'll add features to cover your needs as well (with suggestions by: Stef van Dessel, Bart Smit, Oscar Steenman)
Hostname can now be specified in the configuration (Marcello Scacchetti)
The SMTP banner can now be configured (Marcello Scachetti/bert hubert)
PowerSMTP and PowerPOP init.d scripts now have 'monitor mode' which is great for debugging
Console loglevel can now be tuned
Improvements:
Better feedback if another mailer is already running.
PowerSMTP 'Received' lines now have a proper timestamp.
