MimeDefang is about as efficient as you can get because it multiplexes the 
milter hooks separately as needed between the front/back end processes so it 
doesn't keep a perl process running for every sendmail process and you don't 
have fast operations waiting for slow ones to complete - and it runs 
spamassassin in the backend daemon processes instead of starting a new copy for 
each message.  Plus, it splits out the attachments only once for as many 
scanning operations as you configure.

In theory, you can run MimeDefang as a postfix milter these days but I don't 
know if it actually works.
