I found the best approach is it use many spam fighting tools:

1) My mailserver uses a number of blacklists:

2) My mailserver also has it's own blacklist I've built up, currently
about 500 domains/users.

3) Many spammers configure their mailserver to ID itself with either:
my IP address, my domain name, or my user name.  Use either your
mailserver configuration or procmail to bounce/delete these and it will
cut spam significantly.

4) use a filter like crm114 or spamassassin (called from procmail)

5) a few custom procmail rules to get rid of foreign character sets.  On
sonic's server where I don't run the mailserver I have more procmail
rules then on my own server where I do as much as possible with postfix.
