This is important. If you don't make the change, then all mail appears to come from daemon, which is what you are seeing. I don't believe that the sun version of sendmail that you are running includes the fix so it isn't surprising that the config file works for the sun machine but not for the dec machine. The fix was posted a while back; you can also find it if you look in the sendmail config file that comes with ULTRIX out of the box. For what it's worth; the fix got out to you lot in record time: the total elapsed time between getting the notification of the bug through news and shipping the fix to customers was something like three weeks -- more luck than judgement, it should be said, but for once we got (ever so slightly) ahead of the game. -- -- John Haxby, Definitively Wrong.
