Hello all, I have set up my server using Falko's great howto : Perfect server on Debian lenny with ISpconfig 3. Everything seems fine, except for Postfix. I can send emails, having made a user with ispconfig, fine. But when i try to reply i get this message from the mailer-daemon: Host or domain name not found. Name service error for name=mysite.com type=A: Host not found and from gmail: Delivery to the following recipient failed permanently: [email protected] Technical details of permanent failure: DNS Error: DNS server returned answer with no data What have i not set up correctly? there are no relevant messages in maillog. I have been searching for a reply for the longest time now, with no success: alot of topics on similar problems, but none solve mine. Any help will be appreciated. P.S. wtf? i have tried ZoneEdit Automated SMTP Test and the email it generated actually got to my inbox in squirrelmail... I am totally lost now - it ststed that everything is allright...but i still don't receive from gmail or inbox.lv weird.
