The #1 big change:
- SpamAssassin now *REQUIRES* procmail for local delivery support;
-P option is now the default. Unless you use procmail,
Mail::Audit, KMail, or an MTA-level integration, do not upgrade

SpamAssassin is a mail filter to identify spam.
Using its rule base, it uses a wide range of heuristic tests on
mail headers and body text to identify "spam", also known as
unsolicited commercial email.
