forward problem: mail delivered twice
in [Postfix]
|
From: nik600 on 4 Jan 2010 06:52 Dear all i've installed a postfix server with mysql support. i've also set-up a custom filter script shell that calls spamc and some other custom utils, this script cannot handle multiple recipients, so i've set filter_destination_recipient_limit = 1 The problem that i've experienced is that when i've got an entry like this in the alias table: +---------------------------+----------------------------------------------------------------------+----------------------+---------------------+---------------------+--------+ | address | goto | domain | created | modified | active | +---------------------------+----------------------------------------------------------------------+----------------------+---------------------+---------------------+--------+ | forwarded(a)foo.com | info(a)foo.com,foo(a)yahoo.it,foo2(a)libero.it | foo.com | 0000-00-00 00:00:00 | 2009-12-30 17:37:22 | 1 | +---------------------------+----------------------------------------------------------------------+----------------------+---------------------+---------------------+--------+ Sending an e-mail to forwarded(a)foo.com causes that my script is called 4 times: forwarded(a)foo.com info(a)foo.com foo(a)yahoo.it foo2(a)libero.it and the result is that info(a)foo.com,foo(a)yahoo.it,foo2(a)libero.it receives the mail twice. postconf -n: alias_database = hash:/etc/mail/aliases alias_maps = hash:/etc/mail/aliases broken_sasl_auth_clients = yes command_directory = /usr/sbin config_directory = /etc/postfix daemon_directory = /usr/libexec/postfix data_directory = /var/lib/postfix disable_vrfy_command = yes html_directory = no mail_owner = postfix mailq_path = /usr/bin/mailq manpage_directory = /usr/local/man message_size_limit = 100240000 mydestination = $transport_maps mydomain = foo.com myhostname = mail.foo.com myorigin = $mydomain newaliases_path = /usr/bin/newaliases queue_directory = /var/spool/postfix readme_directory = no relay_domains = proxy:mysql:/etc/postfix/mysql_relay_domains_maps.cf,hash:/etc/postfix/relay sample_directory = /etc/postfix sendmail_path = /usr/sbin/sendmail setgid_group = postdrop smtp_host_lookup = native,dns smtpd_client_connection_count_limit = 50 smtpd_client_restrictions = permit_sasl_authenticated,permit_mynetworks,reject_non_fqdn_sender,reject_rbl_client sbl-xbl.spamhaus.org,reject_non_fqdn_hostname,reject_non_fqdn_recipient smtpd_helo_required = yes smtpd_helo_restrictions = permit_sasl_authenticated, permit_mynetworks, reject_invalid_hostname smtpd_recipient_restrictions = permit_mynetworks,permit_sasl_authenticated,check_sender_access hash:/etc/postfix/whitelist/whitelist_reject_non_fqdn_sender,reject_non_fqdn_sender,reject_non_fqdn_sender,reject_unauth_destination,reject_unauth_pipelining,reject_rbl_client sbl-xbl.spamhaus.org,reject_non_fqdn_hostname,reject_non_fqdn_recipient smtpd_sasl_auth_enable = yes smtpd_sasl_local_domain = smtpd_sasl_path = sasl2/smtpd smtpd_sasl_security_options = noanonymous smtpd_sasl_type = cyrus smtpd_sender_restrictions = permit_sasl_authenticated,permit_mynetworks,check_sender_access hash:/etc/postfix/whitelist/whitelist_reject_non_fqdn_sender,reject_non_fqdn_sender,reject_unknown_sender_domain,reject_non_fqdn_hostname,reject_non_fqdn_recipient strict_rfc821_envelopes = yes virtual_alias_maps = mysql:/etc/postfix/mysql_virtual_alias_maps.cf virtual_gid_maps = static:102 virtual_mailbox_base = /var/spool/postfix/vmail virtual_mailbox_domains = mysql:/etc/postfix/mysql_virtual_domains_maps.cf virtual_mailbox_limit = 100240000 virtual_mailbox_maps = mysql:/etc/postfix/mysql_virtual_mailbox_maps.cf virtual_minimum_uid = 1000 virtual_transport = virtual virtual_uid_maps = static:1000 master.cf smtp inet n - n - - smtpd -o content_filter=filter:dummy 9009 inet n - n - - smtpd -o content_filter=filter:dummy filter unix - n n - 20 pipe flags=Rq user=filter argv=/var/script/filtra_spamc_1.6 -f ${sender} -- ${recipient} ${sasl_username} Is that behaviour correct? How can i avoid to call the custom filter for forwarded(a)foo.com ? Thanks -- /*************/ nik600 http://www.kumbe.it
