Thanks for this.  I have edited the above line to say:

deny    \.ma[dfgmqrsvw]$        Possible Microsoft Access Shortcut 
attack            Microsoft Access Shortcuts are dangerous in email
#deny   \.ma[dfgmqrstvw]$       Possible Microsoft Access Shortcut 
attack            Microsoft Access Shortcuts are dangerous in email

but the .mat attachemnts are still being blocked.

How can I put mail scanner in a debug mode so that I can see it consider 
each rule in turn?

best

Rob
