I am trying to get delay warnings to be sent to users with no success. I've set the delay_warning_time to one hour. If I send a message to an address know to be having problem it gets queued and I can see there is a warning_message_time:
$ sudo postcat -q 834B2800B|grep warning_message_time warning_message_time: Tue Mar 16 15:43:33 2010 However, I'm not seeing any warning message. Is there something else I need to turn on or off? $ postconf mail_version mail_version = 2.3.3 $ postconf -n alias_database = hash:/etc/aliases alias_maps = hash:/etc/aliases command_directory = /usr/sbin config_directory = /etc/postfix daemon_directory = /usr/libexec/postfix debug_peer_level = 2 delay_notice_recipient = <scarvi...@lereta.com> delay_warning_time = 1h disable_vrfy_command = yes error_notice_recipient = <scarvi...@lereta.com> home_mailbox = Maildir/ html_directory = no inet_interfaces = all mail_owner = postfix mailq_path = /usr/bin/mailq.postfix manpage_directory = /usr/share/man message_size_limit = 26214400 minimal_backoff_time = 300s mydestination = $myhostname, localhost.$mydomain, localhost cadmzmx01.lereta.com mydomain = lereta.com myhostname = mx01.lereta.com mynetworks = cidr:/etc/postfix/mynetworks newaliases_path = /usr/bin/newaliases.postfix queue_directory = /var/spool/postfix readme_directory = /usr/share/doc/postfix-2.3.3/README_FILES recipient_canonical_maps = hash:/etc/postfix/recipient_canonical_map relay_domains = closetheloan.com dpsi-corp.com it.lereta.com lereta.com lereta.net lereta.org source.totalflood.com taxandflood.com taxandflood.net taxandflood.org totalflood.com totalflood.net totalflood.org relay_recipient_maps = hash:/etc/postfix/relay_recipients sample_directory = /usr/share/doc/postfix-2.3.3/samples sendmail_path = /usr/sbin/sendmail.postfix setgid_group = postdrop smtp_tls_note_starttls_offer = yes smtp_tls_policy_maps = hash:/etc/postfix/tls_policy_map smtpd_delay_reject = yes smtpd_helo_required = yes minimal_backoff_time = 300s mydestination = $myhostname, localhost.$mydomain, localhost cadmzmx01.lereta.com mydomain = lereta.com myhostname = mx01.lereta.com mynetworks = cidr:/etc/postfix/mynetworks newaliases_path = /usr/bin/newaliases.postfix queue_directory = /var/spool/postfix readme_directory = /usr/share/doc/postfix-2.3.3/README_FILES recipient_canonical_maps = hash:/etc/postfix/recipient_canonical_map relay_domains = closetheloan.com dpsi-corp.com it.lereta.com lereta.com lereta.net lereta.org source.totalflood.com taxandflood.com taxandflood.net taxandflood.org totalflood.com totalflood.net totalflood.org relay_recipient_maps = hash:/etc/postfix/relay_recipients sample_directory = /usr/share/doc/postfix-2.3.3/samples sendmail_path = /usr/sbin/sendmail.postfix setgid_group = postdrop smtp_tls_note_starttls_offer = yes smtp_tls_policy_maps = hash:/etc/postfix/tls_policy_map smtpd_delay_reject = yes smtpd_helo_required = yes smtpd_recipient_restrictions = permit_mynetworks reject_unauth_destination check_client_access cidr:/etc/postfix/accept_by_ip reject_invalid_helo_hostname reject_non_fqdn_helo_hostname reject_unknown_sender_domain check_helo_access pcre:/etc/postfix/helo_check reject_unauth_pipelining check_sender_access hash:/etc/postfix/accept_by_domain reject_rbl_client zen.spamhaus.org check_client_access cidr:/etc/postfix/reject_by_ip check_client_access hash:/etc/postfix/reject_by_client check_sender_access hash:/etc/postfix/reject_by_domain check_recipient_access hash:/etc/postfix/filtered_domains permit smtpd_tls_CAfile = /etc/pki/tls/certs/gd_bundle.crt smtpd_tls_cert_file = /etc/pki/tls/certs/wildcard.lereta.com.crt smtpd_tls_key_file = /etc/pki/tls/private/wildcard.lereta.com.key smtpd_tls_loglevel = 1 smtpd_tls_mandatory_protocols = TLSv1,SSLv3 smtpd_tls_security_level = may tls_random_source = dev:/dev/urandom unknown_local_recipient_reject_code = 550 -- Stephen Carville
