blocking dynamic ip and dialup users with dnsbl lists reduces 60-70% of 
the spam. there is a very good one on an .nl server. for some special 
ones an access list helps. adding a combination of mailscanner and 
spamassassin to sendmail does the rest. the rest which comes thru is not 
really a lot of mails. and all of that stuff is open source and free.

happyly running above things with 50k+ mails / day.
