And, if that's the _only_ piece of MIMEDefang that you want (running 
md_check_agasint_smtp_server in filter_recipient), then you can get the 
same functionality, with less over head (I think), from milter-ahead.

(I do that in MD, but that's because I'm also doing a bunch of other 
things in filter_sender, and such ... if that one piece was all I 
wanted/needed, I'd just use milter-ahead)
