Hi Nathan,
Look at MIMEdefang sendmail Milter it's a very good content/spam filter.
You may also would like to check the commercial CanIt which is based on it.
Assuming you know your way with perl, you can do a lot with it. I'm
using it for spam filtering (with spamassassin) and it's very effective.
Both (MIMEdefang, CanIt) can be found at
