I have installed ISPConfig 3.0.4 and Debian by following the tutorial "The Perfect Server – Debian Squeeze (Debian 6.0) With BIND & Dovecot [ISPConfig 3]
I have to tell that i completely love it. There haven't been any big problems with the installation, everything works fine.
But there is one problem. As i have read, smtp auth is on by default, but the thing is - i can receive e-mails from outside sources, but when i send them from server's squirrelmail, i get this error back to my inbox:
This is the mail system at host srv.site.net.

As far as i undestood from the spamhaus.org link, my ip adress is in a spammers list, and im unfortunately unable to send the mails until ill enable smtp auth.(that's what the suggest in the link) But here's the dilemma, as i mentioned earlier, all the sources say that smtp auth is on by default. So what should i do now? How i fix this problem?
