You could configure 550 as an anti-spam code (see the man page), but
keep in mind that if somebody mis-types an email address it'll just
get deleted and you'll never know.

Note too that you really should have set the envelope header option to
correctly parse multi-drop emails - see the man page again.  Not doing
this can lead to email going places you weren't expecting (like being
dropped on the floor).
