[Mimedefang] Block message with a specific name

[Dan Tulovsky]

Hello.

My boss has requested that I block a certain spam message.  It comes in
with different From addresses, but the From name is always the same:
"Andrea Davis"

How could I block this (either in sendmail, spamassassin, or
mimedefang...).  Preferably the easiest way.  Would just putting that in
the sendmail access list work?

Thank you
Dan
