1. At first when I send mail to my ISPconfig server, I get this replay: "Host or domain name not found. Name service error for name=server1.example.com type=AAAA: Host not found" ok, it is clear message. Try to edit etc/postfix/main.cf (found it on some forum-posts). After that... 2. ... received next "mail for mydomain.com loops back to myself." !!!!! please help ?
NOPE, found it.... hosting , hosting...hmmm I want mails for my domain on separate mail server... only for my domain.. soo I did in ISPConfig for mydomain.com selected external mail server... that was my error. I'll think for solution.
