recently I turned on greylisting on my MXs :
by using that one :
http://www.gasmi.net/gld.html (postfix + mysql)
and really it works rather well, more spam are filtered on a saner
basis than bayasian filters. I still have my bogospam enabled because
the above won't filter spam incoming from mailing lists, mail forwards
(old acounts here and there), open relays etc... but still 90% of spams
are filtered by the above (2950 per day at home) 6% with bogospam and
the cleverest spams have to be manually eliminated (about 15 per days).
with this method you have to manually whitelist some IPs (like lkml)
that produce a lot of valid mails with a lot of different originating
you also need to do that on all your MX, if you don't do it on
secondaries, spam will come from there.
