The messages I am trying to keep from getting to the list are Google 
Calendar invitations (and cancellations).  For these messages or 
specifically targeted non-spam type messages where I have to use the 
spam filters to get rid of them, I would like to send a rejection notice 
giving a reason why the posting is not allowed.  Any spam filters I set 
up for known spam and like messages, I usually just discard the 
message.  I certainly don't want to do any backscatter.

Thanks, Mark.
