I've run sendmail since what was probably day 2 so it wasn't easy for
me to switch to postfix but the anti-spam filtering of postfix are
such a bit better that I bit the bullet.

First and foremost, postfix's filtering is set up more like an IP
filter.  You get to chose the order that the filters get applied and
when to cut short the tests and either reject or accept the email
message without running the rest of the tests.  You also get to do
sanity tests on the HELO string (as well as the traditional client-ip
address and sender-address.)  You can trivially filter for spoofed
mail, where mail claiming to be from your machine comes in via the
external interface.  The filter files can be either hash databases or
lists of regexp's.  (The latter were very painful to do in sendmail
where one needs one table per regexp.)  I've got an example postfix
setup here.  The config files should be fairly readable even for
someone that hasn't ever looked at postfix before.
