Hello, I just finished setting up my server using the guide "The Perfect Server - Debian Squeeze (Debian 6.0) With BIND & Courier [ISPConfig 3]" and after getting everything configured, I ran into a problem with email. I created an email address of "[email protected]" and sent it from SquirrelMail to my Gmail account, and it sent fine, but when I tried to reply back, I got the following failure message: I dont think I missed a step during setup. Can someone tell me where to look to trouble shoot this? Thanks in advance! JustonG
In the header of the returned E-Mail, you'll find much more infos WHY that were happen. Also check the Mail Log files which you could find on Server Terminal here: /var/log/
