Postfix relay problem
I have a somewhat odd problem (I think)
I have two email servers. One is a postfix, the other is a PGP Universal Server. Both are in my DMZ. All email leaving the protected network and entering it, is routed to the PGP server. The PGP server sends all email outbound to the Postfix server. The PGP server retrieves all inbound email from the Postfix server. I believe you would call this a smarthost setup. If I enter the IP of the PGP server into the postfix servers 'access' file and as a REJECT, and run postmap, zero mail can get sent into the domain. Everything get's rejected. I am told this is because the PGP universal is a mail proxy, and checks with the Postfix server for who is allowed to do what. If the postfix server rejects, the universal rejects. If I remove the PGP Universal server from the access table and run postmap, the entire world can relay through that pair of servers. My postconf -n is below, with the real IP's and domain names obfuscated: [root@ciobrrnf2 postfix]# postconf -n alias_database = hash:/etc/aliases alias_maps = hash:/etc/aliases command_directory = /usr/sbin config_directory = /etc/postfix daemon_directory = /usr/libexec/postfix home_mailbox = Maildir/ html_directory = no inet_interfaces = $myhostname, $myhostname.$mydomain mail_owner = postfix mailq_path = /usr/bin/mailq.postfix manpage_directory = /usr/share/man mydestination = $myhostname localhost.$mydomain $mydomain mydomain = somedomain.com myhostname = somehost mynetworks = 111.1.111.111/32,127.0.0.0/8 mynetworks_style = subnet myorigin = $mydomain newaliases_path = /usr/bin/newaliases.postfix notify_classes = resource, software, bounce, delay, policy, protocol queue_directory = /var/spool/postfix readme_directory = /usr/share/doc/postfix-2.3.3/README_FILES relay_domains = relayhost = sample_directory = /usr/share/doc/postfix-2.3.3/samples sendmail_path = /usr/sbin/sendmail.postfix setgid_group = postdrop smtpd_banner = $myhostname ESMTP $mail_name ($mail_version) smtpd_client_restrictions = check_client_access hash:/etc/postfix/access unknown_local_recipient_reject_code = 550 I am anxious for any assistance anyone can provide.
