[Mimedefang] I want MIMEDefang to ignore file attachments

[MimeDefang account]

I have mimedefang 2.33 newly installed on a Solaris 8 system which is 
configured as a mail hub with sendmail 8.12.9.  It currently has an 
ethernet exposed to the internet, and is used to received mail, and 
then pass that mail on to lesser internal systems via an internal 
interface.  Currently, mimedefang+spamassassin is doing a wonderful job 
of tagging spam emails and everyone thinks it is wonderful.

There have also been a couple of incidents where (I am presuming) that 
someone has sent a m$ virus/malicious file.  One example was a .pif 
file.  The user(s) in question received an attachment has been 
quarantined message.  I would like for mimedefang to simply tag spam 
and then pass everything along to the next mail host, to include any 
virus ladden attachments.  As I RTFM'ed and configured my mail setup, I 
felt that my setup would do that (see sendmail.mc line below) from the 
documentation, but I have obviously missed something additional.

What else do I need to do, so I can pass all attachments?

Thanks,

Jerry K
