Milter-null works very well, and should work with recent Postfixes too, 
as they have support for sendmail's milters. Definitely the 
lightest-weight solution.

which can be quite expensive if you have a lot of them coming in. 
Personally I use the MailScanner function (well I would, wouldn't I? :-) 
but I used to get perfectly good results from using milter-null. It 
worked a treat.
