[Mimedefang] Drop mails with pif attachements

[Stefano McGhee]

Hello Matthew,
	I'll take a stab at it.  Might be wrong though :P

Reasonable to want to do that, given all the SoBig.

If you want to simply discard the message, why use action_bounce?  The
problem *might* be that you are trying to do two things: Bounce the message
and discard the message.  My guess is that MD might be confused as to what
to do.  Remove or comment out action bounce and see what happens.  My very
topical assessment of what you have there.

Hopefully, I did!
