Having a list of servers i want to allow to relay mail through my server how do i better configure postfix ????
Add the IP addresses to mynetworks in /etc/postfix/main.cf, e.g. Code: mynetworks = 127.0.0.0/8, 1.2.3.4/32
I have a list of clients i don't want them to go through gmail still using the local smtp , which uses gmail to see mail delivered to the final recipient because mine is a blacklisted dial up account and i have my system clients i want to use local smtp and so gmail . To do this i have commented the relayhost directive pointing to [smtp.gmail.com] and insted i'm using Code: smtp_sender_dependent_authentication = yes sender_dependent_relayhost_maps = hash:/etc/postfix/sender_relayhost To say postfix to use a different smtp relayhost for senders. I have also added: Code: relay_domains = hash:/etc/postfix/relay_domains transport_maps = hash:/etc/postfix/transport With $relay_domains placed also in $mydestination I want to post you also my actual postconf -n: Code: alias_database = hash:/etc/aliases alias_maps = hash:/etc/aliases append_dot_mydomain = no biff = no broken_sasl_auth_clients = yes command_directory = /usr/sbin config_directory = /etc/postfix daemon_directory = /usr/lib/postfix data_directory = /var/lib/postfix debug_peer_level = 3 debug_peer_list = 127.0.0.1, 10.0.0.0/24 delay_warning_time = 8h disable_dns_lookups = yes html_directory = no inet_interfaces = all mailbox_command = mailbox_size_limit = 0 mailq_path = /usr/bin/mailq manpage_directory = /usr/local/man mydestination = $relay_domains, mail.$mydomain ,pop.$mydomain , smtp.$mydomain,www.$mydomain,ns2.$mydomain,ns1.$mydomain ,argo.$mydomain, ftp.$mydomain, localhost.gabrix.ath.cx, localhost.localdomain , localhost mydomain = gabrix.ath.cx myhostname = mail.$mydomain mynetworks = 127.0.0.0/8 , 10.0.0.0/24 newaliases_path = /usr/bin/newaliases queue_directory = /var/spool/postfix recipient_delimiter = + sender_dependent_relayhost_maps = hash:/etc/postfix/sender_relayhost smtp_sasl_auth_enable = yes smtp_sasl_password_maps = hash:/etc/postfix/sasl_passwd smtp_sasl_security_options = smtp_sasl_tls_security_options = $smtp_sasl_security_options smtp_sender_dependent_authentication = yes smtp_tls_CAfile = /etc/postfix/ssl/cacert.pem smtp_tls_cert_file = /etc/postfix/ssl/smtpcert.pem smtp_tls_key_file = /etc/postfix/ssl/smtpkey.pem smtp_tls_loglevel = 2 smtp_tls_session_cache_database = btree:${data_directory}/smtp_scache smtp_use_tls = yes smtpd_banner = $myhostname ESMTP $mail_name (GNULinux/FreeSystem) smtpd_enforce_tls = no smtpd_recipient_restrictions = permit_sasl_authenticated, permit_mynetworks, check_relay_domains, permit smtpd_sasl_auth_enable = yes smtpd_sasl_authenticated_header = yes smtpd_sasl_local_domain = $mydomain smtpd_sasl_path = private/auth smtpd_sasl_type = dovecot smtpd_tls_CAfile = /etc/postfix/ssl/cacert.pem smtpd_tls_CApath = /etc/postfix/ssl/ smtpd_tls_ask_ccert = no smtpd_tls_auth_only = no smtpd_tls_cert_file = /etc/postfix/ssl/smtpcert.pem smtpd_tls_key_file = /etc/postfix/ssl/smtpkey.pem smtpd_tls_received_header = yes smtpd_tls_session_cache_database = btree:${data_directory}/smtpd_scache smtpd_tls_wrappermode = yes smtpd_use_tls = yes soft_bounce = yes tls_random_exchange_name = ${data_directory}/prng_exch tls_random_source = dev:/dev/urandom transport_maps = hash:/etc/postfix/transport To have a better general understanding of my plan . I have split senders also at bind9 dns level making a subdomain of mydomain which i don't want mail to be sent by my local smtp through smtp.gmail.com. Logs look like postfix is using smtp.gmail.com succesfully , for localusers . Code: Jul 15 10:13:57 mail postfix/smtp[4079]: 6F6571079CA: to=<[email protected]>, relay=smtp.gmail.com[66.249.93.111]:25, delay=3.4, delays=0.07/0.03/1/2.3, dsn=2.0.0, status=sent (250 2.0.0 OK 1216109600 z40sm2181928ugc.55) Jul 15 10:13:57 mail postfix/qmgr[3749]: 6F6571079CA: removed But i don't see still mail delivered to Maildir for pop , where i have dovecot , it might be also a bind9 issue , my subdomain is also second MX .
