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.
Procmail
Mail Deliver Agent typically used by Postfix. Do we use amavis instead of it?
Cyrus IMAP
We run Cyrus IMAP on einstein. This can be administrated with "cyradmin". Needs entries in /etc/postfix/master.cf and /etc/postfix/main.cf.
SpamAssassin
Postfix uses SpamAssassin to filter e-mail. Needs an entry in /etc/postfix/master.cf and Procmail configuration
"If SpamAssassin is working, the message will be marked as spam. Note that SpamAssassin only marks messages as spam and that how it does this marking may be affected by your front-end. If you're not using the "spamc" or "spamassassin" program and are using a third-party front-end (especially amavisd), then it may not be completely obvious how spam messages are handled."[1]
AMaVis
Turns out we run amavisd-new, which likes to pretend it's amavisd. Check out their site's info for configuration with Postfix: [2]. Needs an entry in /etc/postfix/master.cf
GNU Mailman
Manages mailing lists.
Web interface on einstein
