hi, i still have some strange behaviour with some mailboxes. i've got a email adress "[email protected]" which is supposed to send autoreplies, but doesn't. that already worked at some point in the past, the only notable change i can think of is that i added a mailman list for the email domain. i can send mails from the box, but don't receive incoming mails. the problem is that postfix expands the name "[email protected]" from the adress "[email protected]", and that mailbox/user doesn't exist. my other mailbox "[email protected]" works fine. i suspect it's got something to do with a (now deleted) mailing list i created in the past that had the same name as the mailbox. but list_lists doesn't show "[email protected]" and ispconfig doesn't either. there must be some config-file somewhere. i hope someone can help me find it.. here's my postconf output: Expand: postconf -n alias_database = hash:/etc/aliases, hash:/var/lib/mailman/data/aliases alias_maps = hash:/etc/aliases, hash:/var/lib/mailman/data/aliases append_dot_mydomain = no biff = no body_checks = regexp:/etc/postfix/body_checks broken_sasl_auth_clients = yes config_directory = /etc/postfix content_filter = amavis:[127.0.0.1]:10024 dovecot_destination_recipient_limit = 1 header_checks = regexp:/etc/postfix/header_checks html_directory = /usr/share/doc/postfix/html inet_interfaces = all inet_protocols = all mailbox_command = procmail -a "$EXTENSION" mailbox_size_limit = 0 maildrop_destination_concurrency_limit = 1 maildrop_destination_recipient_limit = 1 message_size_limit = 0 mime_header_checks = regexp:/etc/postfix/mime_header_checks mydestination = ispconfig.mydomain.com, localhost, localhost.localdomain myhostname = ispconfig.mydomain.com mynetworks = 127.0.0.0/8 [::1]/128 myorigin = /etc/mailname nested_header_checks = regexp:/etc/postfix/nested_header_checks owner_request_special = no proxy_read_maps = $local_recipient_maps $mydestination $virtual_alias_maps $virtual_alias_domains $virtual_mailbox_maps $virtual_mailbox_domains $relay_recipient_maps $relay_domains $canonical_maps $sender_canonical_maps $recipient_canonical_maps $relocated_maps $transport_maps $mynetworks readme_directory = /usr/share/doc/postfix receive_override_options = no_address_mappings recipient_delimiter = + relay_domains = mysql:/etc/postfix/mysql-virtual_relaydomains.cf relay_recipient_maps = mysql:/etc/postfix/mysql-virtual_relayrecipientmaps.cf relayhost = relayhost.mydomain.com smtp_sasl_auth_enable = no smtp_sasl_password_maps = hash:/etc/postfix/sasl_passwd smtp_sasl_security_options = smtp_tls_protocols = !SSLv2,!SSLv3 smtp_tls_security_level = may smtp_tls_session_cache_database = btree:${data_directory}/smtp_scache smtpd_banner = $myhostname ESMTP $mail_name (Debian/GNU) smtpd_client_message_rate_limit = 100 smtpd_client_restrictions = check_client_access mysql:/etc/postfix/mysql-virtual_client.cf smtpd_recipient_restrictions = permit_mynetworks, permit_sasl_authenticated, reject_unauth_destination, check_recipient_access mysql:/etc/postfix/mysql-virtual_recipient.cf smtpd_sasl_auth_enable = yes smtpd_sasl_authenticated_header = yes smtpd_sasl_path = private/auth smtpd_sasl_type = dovecot smtpd_sender_restrictions = check_sender_access mysql:/etc/postfix/mysql-virtual_sender.cf smtpd_tls_cert_file = /etc/postfix/smtpd.cert smtpd_tls_key_file = /etc/postfix/smtpd.key smtpd_tls_mandatory_protocols = !SSLv2, !SSLv3 smtpd_tls_protocols = !SSLv2,!SSLv3 smtpd_tls_security_level = may smtpd_tls_session_cache_database = btree:${data_directory}/smtpd_scache smtpd_use_tls = yes transport_maps = hash:/var/lib/mailman/data/transport-mailman, proxy:mysql:/etc/postfix/mysql-virtual_transports.cf virtual_alias_domains = virtual_alias_maps = hash:/var/lib/mailman/data/virtual-mailman, proxy:mysql:/etc/postfix/mysql-virtual_forwardings.cf, proxy:mysql:/etc/postfix/mysql-virtual_email2email.cf virtual_gid_maps = static:5000 virtual_mailbox_base = /var/vmail virtual_mailbox_domains = proxy:mysql:/etc/postfix/mysql-virtual_domains.cf virtual_mailbox_maps = proxy:mysql:/etc/postfix/mysql-virtual_mailboxes.cf virtual_transport = dovecot virtual_uid_maps = static:5000
