Hi, I installed a postfix relay between a local SMTP server and another relay.
I have the error when email are sent from external (i.e: gmail) to my internal domain : Recipient address rejected: User unknown in local recipient table Here is my main.cf: disable_dns_lookup = yes queue_directory = /var/spool/postfix command_directory = /usr/sbin daemon_directory = /usr/libexec/postfix mail_owner = postfix myhostname = smtpsrv mydomain = toto-internal.com inet_interfaces = all mydestination = $mydomain, $myhostname, localhost.$mydomain, localhost local_recipent_maps = unknown_local_recipient_reject_code = 550 mynetworks = hash:/etc/postfix/mynetworks transport_maps = hash:/etc/postfix/transport debug_peer_level = 2 sendmail_path = /usr/sbin/sendmail.postfix newaliases_path = /usr/bin/newaliases.postfix mailq_path = /usr/bin/mailq.postfix setgid_group = postdrop smtpd_banner = SMTP Relay - Unauthorized please unlog immediately !!! relayhost = 192.x.x.x fallback_relay = Transport file: .toto-internal.com smtp:[172.x.x.x] toto-internal.com smtp:[172.x.x.x] * smtp:[192.x.x.x] Mynetworks: #external relay 192.x.x.x OK #internal mail server 172.x.x.x OK #postfix itself 192.x.x.y Any idea ? Thanks in advance.
