OK first things first, you don't need milter ahead as this  
functionality is built in to Postfix natively http://www.postfix.org/ 

Secondly, I am running 2.3 rc3 and as of this moment I am see no  
problems with any corrupt mail but who knows what the future brings  
when Wietse brings in message altering milter support. All we can do  
it try it and see! I suspect that as MailScanner now uses the hold  
queue, which is a form of approved interface to Postfix (IMHO) it is  
unlikely to break but we shall see...
