    Default Just Installed, email problems - 554 Relay Access Denied

    Hi,

    Untangled is working great, except that our employees can't seem to send out email (from a postfix server - thats not behind untangled) to domains other than it's physical one.

    Say our domain is blah.com

    My employees can send email from joe@blah.com to ted@blah.com , but not from joe@blah.com to ted@gmail.com

    We get : 554 <*@gmail.com>: Relay access denied

    Anyone know how to solve this?

    Cold one on me if so.


    [SOLVED - 10/16/2009] - It was my postfix not allowing smtpd relay, only certain IP's were listed in there, by someone that set this system up before my time. It was in /mailserver/etc/postfix/ postconf -n , then postconf -e 'mynetworks = CIDR IP STYLE HOST' then /etc/init.d/postfix reload

    Thanks for all your interest in helping me, I should now be of some assistance to others !!

    Just an update to this, if we login to 'squirrelMail' - the webmail client for postfix , then we can send email out to anyone.

    It's through outlook, that we can't get mail out to others.

    Hi,
    What modules are you running in untangle?
    are the outlook clients connecting over SMTP to the mailserver?

    have you change or deleted the default no rack policy for SMTP ?

    I'm running all of the modules except the ones that are paid for. Outlook clients are indeed connecting over SMTP.

    I haven't changed or deleted the default no rack policy for smtp -- is that the problem right there? If so I feel like a moron, I just panicked because everyone has been calling me about this, ha

    well the thing is that by default there is a no rack policy that forces all smtp traffic in to a empty rack (meaning that untangle dose not filter smtp traffic to the outside)

    Where is the server located ?
    On Untangles External interface or dmz?

    The server isn't apart of the untangle network. Heres what my net looks like


    [dsl-modem]----[wrt54g-router]:192.168.21.1-----------[untangle]192.168.21.70-----switch-----employees

    The mail server is on a T1 line that is in our building, but not behind untangled.

    So Untangle is in bridge mode?

    If you connect a pc to the wrt54g router dose it connect fine to the maill server?
