Could you show what you have written to those name service records? You can replace the actual domain name with mydomain if you want. I assume you are issuing those nslookup commands on your windows workstation, is this so? Please copy and paste the commands you write. Have you waited enough time to let the name service info to propagate to name servers around the world? Instead of nslookup on the windows workstation, you can use command host on the server where you run ISPConfig.
special thinks for you reply solved by 1-create A record as smtp instead of smtp.mydomaine. 2- create cnam record : smtp.mydomain best regards
