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:
Technical details of permanent failure:
PERM_FAILURE: SMTP Error (state 9): 554 5.7.1 <firstname.lastname@example.org>: 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.
