[cobalt-users] Unknown User MAILER-DAEMON Question



Getting a lot of reason: 550 user@xxxxxxxxxxxxxxxxx unknown mail from some
recently move sites.
I personally want to receive a notice when mail is sent to an unknown user
at my domain however,
owner of other sites does not. So here's the question.
Is there a configuration solution that would accomplish this?
Either a sendmail flag set by domain or setting catch all account that
bounces mail/spam back to
sender as user unknown.
Any thoughts?
