    I am running the Perfect Ubuntu 7.10 server setup. I installed and everything worked fine. My needs changed and I my mail server was being hosted at my registrar site and I have updated the mx record to point there.

    My problem is this: My website sends mail to users upon registration and that functions as advertised. However, when I attempt to test the system by sending mail to [email protected], i get the following email error message:

    host[xx.xx.xx.xx] said: 553 sorry, that domain
    isn't allowed to be relayed thru this MTA (#5.7.1) (in reply to RCPT TO

    It almost looks as though the mail server is not redirecting mail to users that were on the system to the new mail server at the registrars site.

    Any help would be appreciated as I need to solve this problem, its a production server.

    Did you set your domains to "External Mailserver" in ISPConfig? You might also have to do this for the Co-Domains.

    Thank you for you assistance with this.

    I had found that recommendation is another post previously, so I did set the domains to external mail in ISPConfig, but the problem still exists.

    Other ideas?

    Did you enable "Server requires authentication" in your email client?

    I have enabled "Server requires authentication" on my client, but the mail never seems to route so that I may fetch it. The error seems to indicate that it is being refused by my mail server when a test message is sent from my web server (same physical machine).

    Please run
    postconf -e 'mydestination = /etc/postfix/local-host-names'
    /etc/init.d/postfix restart
