Hello;
My users NDR's are not arriving until the 5 day retry period has lapsed, creating issues whereby time critical emails are not getting out due to their unawareness of this matter. I've tried several changes in my main.cf, none seem to do the trick for me. Here is some of my postconf output, hopefully the important/relevant parts: mta1:/etc/mail# postconf | grep reject 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_delay_reject = yes smtpd_recipient_restrictions = permit_mynetworks, reject_unauth_destination, check_sender_access dbm:/etc/mail/blocked_senders, reject_rbl_client ST-HJWR-78HYW-AH34-UUG6-GZU5C-TY56.y.mail-abuse.com smtpd_reject_unlisted_recipient = yes smtpd_reject_unlisted_sender = no smtpd_sender_restrictions = reject_unauth_pipelining, reject_unknown_sender_domain, reject_non_fqdn_sender, check_recipient_access dbm:/etc/mail/access unknown_address_reject_code = 550 unknown_client_reject_code = 450 unknown_hostname_reject_code = 550 unknown_local_recipient_reject_code = 450 unknown_relay_recipient_reject_code = 550 unknown_virtual_alias_reject_code = 550 unknown_virtual_mailbox_reject_code = 550 unverified_recipient_reject_code = 450 unverified_sender_reject_code = 450 Anything I must change here in order for outbound email to get quick NDR's? Thank you, .vp
