This is the set of programs that service NPG e-mail.

Postfix

Centralized set of programs to send/recieve mail, as well as put recieved mail through spam/virus filters. The RPM is pretty good in that it automatically puts entries for some of the below programs in the appropriate configuration files. Sometimes it's necessary to un-comment them, though.


Dovecot

We run dovecot as our mail server. We're using a pretty much default setup, for ease of administration. The dovecot website has all necessary documention, and most of the system is fairly self-explanatory.

SpamAssassin

Postfix uses SpamAssassin to filter e-mail. Needs an entry in /etc/postfix/master.cf and Procmail configuration

Presently, we only mark spam with some header flags, and by prepending "[SPAM] " to the subject of spammy messages. Due to issues with forwarding spammy messages, we are quietly purging all spam mail. Because we have fairly conservative settings, this should not cause any problems.

GNU Mailman

Manages mailing lists.
