  Here, with the a!b@c ambiguity comes a real downfall in sendmail.  All the
  other complaints pale under this one.  Sendmail	 doesn't have any way
  of routing mail depending on how the site received the mail.  You don't
  know how many times I've wanted to do things to addresses depending on how
  they were received!

  Now the biggy..... Has anyone out there got any ideas on how to make
  sendmail be responsive to how it received its mail?

What I did for the University of Washington mailer was simple but
effective.  I wrote a separate /bin/rmail that just translates
destination addresses of the form "a!<anything>" to "<anything>@a.uucp".
If necessary, all '@' in "<anything>" can be turned into '%' also
(although I hate having to do that).
