Or does reject_unlisted_recipient get disabled completely when smtpd_reject_unlisted_recipient=no?You can then use "reject_unlisted_recipient" explicitly at the appropriate stage in the recipient restrictions.
Okay, I understand why doing any of this in DATA is bad and I should have realized that. Just to clarify in trying to achieve my end goal, is there any way to get milters to run before postfix would evaluate reject_unlisted_recipient in the RCPT command?
