I've always liked MimeDefang with sendmail - and these days it should be possible to make it work with postfix. Basically you connect it as a milter to the stock MTA - without many other config changes there. Then you add all of the scanning and control steps in a small snippet of perl (with examples available for most of the things you would want to do). I'd recommend glancing through this document: http://www.mimedefang.org/static/mimedefang-lisa04.pdf for an overview of what you need to do even if you decide to use other tools. But, mimedefang is very effecient, at least with sendmail because it will unpack attachments once even if you do a number of different scans for spam/viruses, etc., and it hooks the milter interfaces for each operation separately through a multiplexer so you don't start a big perl process for every deliver and you don't keep it tied up for the steps that don't need it (see diagrams on pgs 16 and 113 of that pdf for the concept). -- Les Mikesell lesmikesell at gmail.com
