What MTA do you run?
seifried.org Mail looks like this:
Internet
|
Firewall - OpenBSD with spamd (defaults) and very agressive
greytrapping.This catches about 90% of my spam (the main idea is to reduce
load on spamassassin and make sure I'm talking to a real mail server). For
example if you try to email kurs@seifried.org or kuru@seifried.org you get
black listed (so often spammers go in alphabetical order hit those before
kurt@seifried.org) I also have a script that checks the maillogs for
undeliverable addresses and adds those (about 3000 in all added, very few
new ones being added now).

Incoming MX servers - two servers running Postfix with various anti-spam
things enabled.
|
Mail server - Postfix server with spamassassin and some procmail filtering
for attachments/etc to my personal accounts. IMAPS server for mail
retrieval.
So currently I have two main lines of defense against spam: OpenBSD spamd
and spamassassin. I have not yet enabled Bayes filtering, which would
provide an additional level of spam filtering (I get 2-3 spams a day to my
accounts so it's not enough to bother me enough to setup Bayes filtering).
