This rarely happens here, but one of our users recently sent out
a mail message with LOTS of recipients.  Unfortunately, this
generated multiple copies of the data file.  Being a (somewhat)
conscientious network user, I was wondering WHY?  I have the
'm' flag set in the "sendmail.cf" file (for "smail" -- our external
mailer).  Does this option only work if the users are on the same
host?  All the messages first get routed to our only mail link
(rochester).  75% of the remaining messages then go on to rutgers.
Is mail not smart enough to break up "To:" lists when mail paths
diverge?  Why not (not that I volunteer mind you)?  Since the above
mentioned user may be setting up a mailing list in the near future,
this seems like a good time to solve this potential problem -- or
ignore it if there is no fix for it, but at least I've done my best...

BTW, what, pray tell, does the 'm' flag REALLY do -- have multiple
addresses only for the local host?  Only for messages where the
path is identical (i.e. destination host is the same)?
