Relay access denied to a 2nd. domain

[sur58]

Hi to all,

I've installed Ispconfig with the perfect ubuntu server setup, and it works great with the 1st domain.

Now I've created a 2nd domain, and when i try to send an email from gmail, hotmail or other external email server, my server response is:

This is an automatically generated Delivery Status Notification

Delivery to the following recipient failed permanently:

webmaster@mydomain.com

Technical details of permanent failure:
PERM_FAILURE: SMTP Error (state 9): 554 5.7.1 <webmaster@mydomain.com>: Relay access denied

I've been searching in forums for the last couple of hours, but i can't find a way to fix that problem.

Anyone can help me? Thanks in advance.

Now it works...!!!!

What I've done is to add "mydomain.com" in /etc/postfix/local-host-names"

Thanks guys....!!!
