When using the "smtpd_delay_reject = yes" option, all log messages indicate RCPT stage rejection. e.g. "... NOQUEUE: reject: RCPT from ..."; regardless of which type of restriction an option is listed under.
For instance a rejection based on the following will indicate RCPT rather than CONNECT as it would if delay reject was not used. smtpd_client_restrictions = reject_rbl_client zen.spamhaus.org Is it possible to have Postfix log with the proper indication of where the restriction is list rather the stage at which it is actually check and carried out? So restriction listed in the "smtpd_client_restrictions" section would indicate CONNECT, and restrictions listed in "smtpd_helo_restrictions" section would indicate HELO, "smtpd_sender_restrictions" indicate FROM, "smtpd_recipient_restrictions" indicate RCPT, and so forth.
