Greylisting will kill most of the spam.
The first time an IP sends an email it will get a soft error telling
it to come back later. When it indeed comes back later you accept the
email and put the senders IP in the whitelist (for some time say 30 days).

An easy way to get greylisting is using qpsmtpd http://smtpd.develooper.com/
plus you can easily customize it with plugins written in perl.

Alas it has legal problems in .de as it intentionally slows down the
communication, which is not allowed (although i don't know how this
would end up in a court since there are enough arguments for it).
