If it's not just for personal use, but on a mailserver with quite some
users I'd like to happily recommend ASSP. http://assp.sf.net/

It's *not* easy to setup, but after you've gone through all the options
and learned about it, it is indeed the most deadly spam killer around.

It's very flexible, with a lot of options. and active development.
You can do regex filtering on subject, header, body, data etc.
It has a nice web GUI, but you can put several things in different
configuration files if you like.

One interesting option e.g. is to do delaying only for emails which have
a certain "griplist" score.
Another interesting option is the "Test mode", you can run it in front
of e.g. postfix and just monitor it without doing any real filtering yet.
