This is a known configuration "gotcha" for users of ISPs like Demon (and it
_is_ annoying!)  I believe the sendmail.cf from this site gives a tidier way
to solve the problem.  All mail to unrecognised users are relayed to
postmaster.

You simply have to define LUSER_RELAY to be local:postmaster.

Once you have your recognised users set up, it's probably wise these days to
turn off this behavior.
