Note: milter-ahead isn't free, it's one of 4 of the snertsoft milters that costs 
money. a site license is 90 euros:

You might also wish to read this thread about sms-sav vs milter-ahead:

I flicked both of these options and went for scam-back, which has the added features of doing the recipient checks against _any_ remote smtp server (admin definable).

scam-back is also open source and c-coded, so is fast. It works with sendmail as a milter.

Michael.
