Look in your maillog for the envelope sender.  It may well be quite 
different from the From: in the message itself.  You need to work with 
the envelope sender and not the message sender.  Use the following 
option to get it in the message headers of every email processed my MS:
Add Envelope From Header = yes

When you have the envelope sender, use that value (maybe with wildcards) 
in your whitelist rule.
