I just spent an hour or two browsing the UCB Mail code.  My eyes are
tired, I am tired, and my wife is ticked off I've been ignoring her.
It dawns on me that someone might have fixed what I perceive as a
problem and so I share it with you.

If I receive a mail message from, say, systemA.domain!user which is
also addressed to grover and oscar on systemA and to user cookie on my
system (look, I have kids, okay?), the mail header I see looks
something like this:

  From systemA.domain!user Fri Apr 26 19:50:25 1985

  From: systemA.domain!user
  To: grover, oscar, decuac!avolio, decuac!cookie
  Subject: Hello...

If I reply with the 'r' command, I get a To: line like this...

 To: systemA:domain!grover, systemA:domain!oscar, cookie, systemA.domain!user

Now, since really I wish it would just leave my little periods alone
all the time (as it does for the original poster -- note it doesn't
rewrite the originator -- just the other addressees who are relative
to user's site and domain) I've been trying to find where it does this
little bit of magic.  I grep-ed!  I browsed!  I read.  And I hope
someone else did the same with more luck.  I know one can fix this
(easily) in sendmail.cf, but one really shouldn't have to.  Ideas?
