    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 'user1@gmail.com'. Subject 'test', Account: 'mail.internal.account', Server: 'server.internal.account', Protocol: SMTP, Server Response: '554 5.7.1 <user1@gmail.com>: 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

    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

    smtpd_recipient_restrictions = permit_mynetworks, reject_unauth_destination, reject_non_fqdn_recipient

    smtpd_sender_restrictions =
    transport_maps = hash:/etc/postfix/transport
    unknown_local_recipient_reject_code = 550

    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

    Thanks!

    Top dog...I knew it would be something simple.

    Thank you for showing me the way!!!!
