That of course turns any rejection which comes after this restriction into a deferral, and that's not quite what you said you want. There are ways to apply it only to unknown recipients. I would move any spam-blocking restriction to smtpd_client_restrictions, after any necessary permit_* restrictions and before check_recipient_access. Then the unknown recipient rejection, which happens in smtpd_recipient_restrictions, will be subject to defer_if_reject. -- http://rob0.nodns4.us/ -- system administration and consulting Offlist GMX mail is seen only if "/dev/rob0" is in the Subject:
