	I have been having similar problems since I upgraded our 4/330 to
a 630MP running 4.1.2.  Outgoing mail seems to work just fine, but every
once in a while incoming network mail gets returned to the sender with a
550 user unknown error.  There was a fix posted to comp.sys.sun.hardware a
while back which has helped, but not eliminated the problem for me.  Now I just
re-start sendmail and things will work ok for a while.  Here's the fix:
