Dynamic Relay Authorization Control
Dynamic Relay Authorization Control (DRAC) ties into your POP/IMAP server to temporarily grant SMTP relay access to hosts that successfully authenticate and pick up mail (the assumption being these hosts will send mail, and not abuse this privilege. You can get it from: http://mail.cc.umanitoba.ca/drac/index.html.
procmail (the default local delivery agent typically) has a wide variety of features that can be used to help "sanitize" email. More information on this is available at: ftp://ftp.rubyriver.com/pub/jhardin/antispam/procmail-security.html.
