Looks like my registrar screws up when I asked them to insert a reverse DNS record for my mail server and they have not corrected it. But I cannot see this as being my problem, but I really appreciate the find Talisman, I'm in the process of getting that corrected. I've checked the IP addresses and the seem correct.
So it seems when my ISP has been inserting reverse DNS records they had made a mistake when registering other companies IP addresses 212.159.96.43 and 212.159.96.48
Please post a screenshot of both tabs of this dns record in ISPConfig as they are now, so we can check them.
Check if the zone file is actually created in your dns servers; if there is an error it will be renamed with .err and your server won't answer for the zone. You can rename such a file without the .err and restart named to see what the error is ) then fix the error or rename to .err again to be able to start named).
