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).
