Ok, I'm still having problems with UUCP. Quite often, any incoming
UUCP mail gets lost by the system.

I think I've tracked down the problem to /usr/lib/sendmail. However,
it may have something to do with rmail.

Original problem:
  Mail would arrive at machine, only to get lost, with a return
  message going back to agent on the sending machine with a subject of
  "uuxqt cmd (rmail fozztexx) status (signal 0, exit 208)"

What I did next:
  I located a newer version of rmail(4.15 5/31/90) and hacked it to
  send the appropriate flags to sendmail (discovered with strings
  /bin/rmail)

  Mail was still getting lost, only now, I wasn't getting those
  messages back from uuxqt indicating anything went wrong.

So then:
  I hacked up the rmail to log every little detail to a file, and to
  fork into sendmail, so that I could even log sendmail's return code.
  Well, sendmail was getting exec'd ok, and was even returning a
  status code of 0. Still losing mail though.

So today I:
  changed /bin/rmail to be a link to /usr/lib/sendmail. Hey, I figured
  even if the header looked like crap, at least I'd get the body.

  So I sent off a message to barf!nvcc!barf!nvcc!barf!nvcc!fozztexx
  (barf is the name of the machine I call, nvcc is my machine, and
  fozztexx is my account), to test out UUCP, once again. 

  Well, after the message came back to nvcc the second time, it
  disappeared without a trace. No errors or anything.

Also:
  barf and nvcc are NeXTs running 2.1 and configured as a mail server
  (ie.  sendmail.cf is a link to sendmail.mailhost.cf) and all the
  changes I made to nvcc I also made to barf (like changing the rmail,
  as well as making it a link).

So can anyone make this problem go away? Can I ftp a newer/better
version of sendmail that will make it stop doing this? Do I need to
change my sendmail.cf file to make it stop?

This only happens with UUCP. When any of the machines connected thru
the ethernet send mail, it always arrives succesfully. Of course, they
just transfer it to nvcc, so it goes from nvcc to nvcc.
