Just thinking out load but is this what might be happening.... 1) message comes in for unknown [EMAIL PROTECTED] 2) postmaster returns to sender 3) sender is mailing list that does except from [EMAIL PROTECTED] and returns to [EMAIL PROTECTED] 4) postmaster forwards to designated local admin 5) designated admin mailbox fills up with postmaster error messages Does this sound like the possible scenario? The headers would confirm but I can't get at them until tomorrow. If this is the case then maybe an smtpd_check_rules block may be the solution. Block all emails coming in on the external interface addressed directly to the postmaster. Don't know if this might 'break' something.
