Running Postfix 2.7.x I have set delay_warning_time to 4 hours, but was wondering if it is possible to send out two or more bounce messages about a delayed message?
What I am aiming for is, that if a message can not be delivered to the destination, then Postfix will inform the sender immediately, or close to immediately, about it. Then later on, if the message gets delivered before max query_time is reached, sends a confirmation to the user, that the message now have been delivered to the destination. I have tried to find the answer by searching the net and reading man pages but without any luck, since I do not really know what to search for, so any pointers will be greatly appreciated. Thanks If need be, a postconf -n from the server: --- alias_maps = hash:/etc/aliases bounce_template_file = /etc/postfix/bounce.cf broken_sasl_auth_clients = yes config_directory = /etc/postfix delay_warning_time = 4 disable_vrfy_command = yes inet_interfaces = all maximal_queue_lifetime = 15 myhostname = <removed> mynetworks = 127.0.0.0/8 recipient_canonical_classes = envelope_recipient recipient_canonical_maps = hash:/etc/postfix/pfix-no-srs.cf, tcp:127.0.0.1:10002 relay_domains = proxy:mysql:/etc/postfix/relay_domains.cf relay_recipient_maps = proxy:mysql:/etc/postfix/relay_recipient_maps.cf sender_canonical_classes = envelope_sender sender_canonical_maps = hash:/etc/postfix/pfix-no-srs.cf, tcp:127.0.0.1:10001 smtp_tls_security_level = may smtp_tls_session_cache_database = btree:$data_directory/smtp_tls_session_cache smtpd_data_restrictions = reject_unauth_pipelining reject_multi_recipient_bounce permit smtpd_helo_required = yes smtpd_recipient_restrictions = permit_mynetworks permit_sasl_authenticated reject_unauth_destination warn_if_reject reject_invalid_helo_hostname warn_if_reject reject_non_fqdn_helo_hostname warn_if_reject reject_non_fqdn_sender warn_if_reject reject_non_fqdn_recipient warn_if_reject reject_unknown_sender_domain warn_if_reject reject_unknown_recipient_domain warn_if_reject reject_rbl_client truncate.gbudb.net check_policy_service unix:private/spfcheck permit smtpd_sasl_auth_enable = yes smtpd_sasl_exceptions_networks = $mynetworks smtpd_sasl_path = private/auth smtpd_sasl_security_options = noanonymous smtpd_sasl_type = dovecot smtpd_tls_ask_ccert = yes smtpd_tls_cert_file = /etc/ssl/self-signed/smtpd.crt smtpd_tls_key_file = /etc/ssl/self-signed/smtpd.key smtpd_tls_loglevel = 1 smtpd_tls_received_header = yes smtpd_tls_security_level = may smtpd_tls_session_cache_database = btree:$data_directory/smtpd_tls_session_cache tls_random_source = dev:/dev/urandom transport_maps = hash:/etc/postfix/transport virtual_alias_maps = proxy:mysql:/etc/postfix/mysql_virtual_alias_maps.cf virtual_gid_maps = static:5000 virtual_mailbox_base = /home/vmail virtual_mailbox_domains = proxy:mysql:/etc/postfix/mysql_virtual_domains_maps.cf virtual_mailbox_maps = proxy:mysql:/etc/postfix/mysql_virtual_mailbox_maps.cf virtual_minimum_uid = 5000 virtual_transport = dovecot virtual_uid_maps = static:5000 ---
