Hi all, I'm recently having a big issue with postfix.
I have an alias that includes all users from my organization, there is no loop here, i'm sure. When somebody sends an email to that alias, all users from my organization keep receiving this message 10, 20, 30, 40 times, 40 times the same message that was sended only once. Here is my configuration: alias_database = hash:/etc/aliases alias_maps = hash:/etc/aliases append_dot_mydomain = no biff = no body_checks = regexp:/etc/postfix/body-checks.regexp broken_sasl_auth_clients = yes command_time_limit = 4h config_directory = /etc/postfix debug_peer_level = 2 defer_transports = header_checks = regexp:/etc/postfix/header-checks.regexp inet_interfaces = all inet_protocols = all mailbox_command = procmail -a "$EXTENSION" mailbox_size_limit = 500000000 message_size_limit = 5000000 mydestination = $myhostname, $mydomain, localh...@$mydomain mydomain = example.com.br myhostname = smtp-gw.example.com.br mynetworks = 127.0.0.0/8,192.168.0.0/24 myorigin = /etc/mailname recipient_delimiter = + smtp_tls_session_cache_database = btree:${queue_directory}/smtp_scache smtpd_banner = $myhostname ESMTP smtpd_helo_required = yes smtpd_helo_restrictions = permit_mynetworks ,permit_sasl_authenticated ,check_client_access hash:/etc/postfix/helo-whitelist ,check_helo_access regexp:/etc/postfix/helo-invalid.regexp ,reject_invalid_hostname ,reject_non_fqdn_hostname ,reject_unknown_hostname smtpd_recipient_restrictions = permit_mynetworks ,permit_sasl_authenticated ,check_client_access hash:/etc/postfix/helo-whitelist ,reject_unauth_destination ,check_sender_access hash:/etc/postfix/sender-blacklist ,reject_unauth_pipelining ,check_policy_service unix:private/policy ,check_policy_service inet:127.0.0.1:60000 smtpd_sasl_auth_enable = yes smtpd_sasl_local_domain = smtpd_sasl_security_options = noanonymous smtpd_tls_cert_file = /etc/ssl/certs/ssl-cert-snakeoil.pem smtpd_tls_key_file = /etc/ssl/private/ssl-cert-snakeoil.key smtpd_tls_session_cache_database = btree:${queue_directory}/smtpd_scache smtpd_use_tls = yes I'm running ubuntu 8.04 (Upgraded from 7.04 -> 7.10) with postfix version 2.5.1-2ubuntu1.2. Any help will be really appreciated. Thanks in advance. []'s Gabriel.
