Hi, Just setup The Perfect Server - CentOS 5.4 x86_64 [ISPConfig 3] with mostly no issues and must congratulate Falco for doing that. However, I'm having what seems to be a common issue with Postfix and after trawling thru cannot find a solution that will work for me. I can send an email using Outlook Express to an internal email address but cannot send one to gmail as I get the following: The message could not be sent because one of the recipients was rejected by the server. The rejected e-mail address was '[email protected]'. Subject 'test', Account: 'mail.internal.account', Server: 'server.internal.account', Protocol: SMTP, Server Response: '554 5.7.1 <[email protected]>: Relay access denied', Port: 25, Secure(SSL): No, Server Error: 554, Error Number: 0x800CCC79 My main.cf is as follows: Code: alias_database = hash:/etc/aliases alias_maps = hash:/etc/aliases broken_sasl_auth_clients = yes command_directory = /usr/sbin config_directory = /etc/postfix daemon_directory = /usr/libexec/postfix debug_peer_level = 2 html_directory = no inet_interfaces = all mail_owner = postfix mailq_path = /usr/bin/mailq.postfix manpage_directory = /usr/share/man mydestination = $myhostname, localhost.$mydomain, localhost mydomain = internal.account myhostname = server.internal.account mynetworks = 127.0.0.0/8, internal.accountIP/32 newaliases_path = /usr/bin/newaliases.postfix queue_directory = /var/spool/postfix readme_directory = /usr/share/doc/postfix-2.3.3/README_FILES relay_domains = $mydomain relayhost = sample_directory = /usr/share/doc/postfix-2.3.3/samples sendmail_path = /usr/sbin/sendmail.postfix setgid_group = postdrop smtpd_recipient_restrictions = permit_mynetworks, reject_unauth_destination, reject_non_fqdn_recipient smtpd_sasl_auth_enable = yes smtpd_sasl_security_options = noanonymous smtpd_sender_restrictions = transport_maps = hash:/etc/postfix/transport unknown_local_recipient_reject_code = 550 My /etc/postfix/transport file is as follows: Code: * smtp:mail.internal.account My master.cf is as follows: Code: # service type private unpriv chroot wakeup maxproc command + args # (yes) (yes) (yes) (never) (100) # ========================================================================== smtp inet n - n - - smtpd #submission inet n - n - - smtpd # -o smtpd_enforce_tls=yes # -o smtpd_sasl_auth_enable=yes # -o smtpd_client_restrictions=permit_sasl_authenticated,reject smtps inet n - n - - smtpd # -o smtpd_tls_wrappermode=yes # -o smtpd_sasl_auth_enable=yes # -o smtpd_client_restrictions=permit_sasl_authenticated,reject #628 inet n - n - - qmqpd pickup fifo n - n 60 1 pickup cleanup unix n - n - 0 cleanup qmgr fifo n - n 300 1 qmgr #qmgr fifo n - n 300 1 oqmgr tlsmgr unix - - n 1000? 1 tlsmgr rewrite unix - - n - - trivial-rewrite bounce unix - - n - 0 bounce defer unix - - n - 0 bounce trace unix - - n - 0 bounce verify unix - - n - 1 verify flush unix n - n 1000? 0 flush proxymap unix - - n - - proxymap smtp unix - - n - - smtp # When relaying mail as backup MX, disable fallback_relay to avoid MX loops relay unix - - n - - smtp -o fallback_relay= # -o smtp_helo_timeout=5 -o smtp_connect_timeout=5 showq unix n - n - - showq error unix - - n - - error discard unix - - n - - discard local unix - n n - - local virtual unix - n n - - virtual lmtp unix - - n - - lmtp anvil unix - - n - 1 anvil scache unix - - n - 1 scache # # ==================================================================== # Interfaces to non-Postfix software.

Relay Access Denied. I just tried removing: reject_unauth_destination, reject_non_fqdn_recipient to leave me with: smtpd_recipient_restrictions = permit_mynetworks and now the message sending just hangs, sits there and eventually times out whilst trying to connect to the mail server. I must point out that I'm trying to set this up so that we can have all mail leave thru this Centos box via the smtp server before going through the firewall. Regards.
you have misconfigured your server, you are allowing only the mail server itself to relay mail. To be able to relay mail from your other machines, you need to add your subnet to mynetworks
