Some dude on slashdot’s mail setup that I want to remember:

• SMTP + SASL_Authentication over TLS
• Amavisd+spamassassin+clamav
• LDAP+Kerberos/SSH user authentication
• IMAP+SSL and IMAP-SSL(localhost) support

This is somewhat similar to mine with the exception of a couple things that I’d like to implement like the SASL for SMTP and clamav (Anti-Virus for email).
