Sorry John, I should have explained.  I have been on this list so long
that I forget newbies still show up and need to be brought up to speed.

Sendmail (version 8.9.3 anyway) will advertise the -outgoing alias in 
the "Received: " headers it adds to messages if you do not make each
address appear to be addressed to multiple recipients.  Using the 
nobody address (which should have an alias to /dev/null), fulfills 
that requirement without actually sending the message anywhere else. 

Example aliases for the ,nobody 
test: "|/usr/local/majordomo/wrapper resend -l test test-list,nobody"
