hello,
i wish to change the response code for rejection of unknown user from 450 to 550. all user accounts are held in dbmail and the address/user maps are via pgsql queries. i have recently rearranged the email accounts and deleted some but senders are not getting any useful indication that the accounts are closed as the response code is 450 . the active 'reject' response codes from postconf are access_map_reject_code = 554 invalid_hostname_reject_code = 501 maps_rbl_reject_code = 554 message_reject_characters = multi_recipient_bounce_reject_code = 550 non_fqdn_reject_code = 504 plaintext_reject_code = 450 reject_code = 554 relay_domains_reject_code = 554 smtpd_reject_unlisted_recipient = yes smtpd_reject_unlisted_sender = no unknown_address_reject_code = 450 unknown_client_reject_code = 450 unknown_hostname_reject_code = 450 unknown_local_recipient_reject_code = 550 unknown_relay_recipient_reject_code = 550 unknown_virtual_alias_reject_code = 550 unknown_virtual_mailbox_reject_code = 550 unverified_recipient_reject_code = 550 unverified_sender_reject_code = 450 your assistance will be appreciated. regards john
