Last time I rebuilt my mail server I let my spam filtering configuration
get very simple, it's now:

1. Postfix's internal sanity checks (eg, real hostname, real address, etc.)

2. A custom access list I wrote many years ago (essentially a DUL)

3. A set of access lists equivalent to SPF for major webmail domains

4. A few RBL's: Spamhaus Zen, and the Barracuda RBL (almost all are
blocked by the first, very few by the latter)

That combination results in almost a little spam as a full spamassassin
setup used to, and has the benefit of rejecting everything at SMTP time,
not elsewhere.

The only maintenance required is some very occasional (~1/year) work to
delete now obsolete entries from the custom access list
