When I installed OwnCloud on my Hyper-V Server I made the setup with a domain as I let point at OwnCloud ip.
But I want to use another domain instead of the first. So I want to edit the file where the domain name is stored, but I can't find the file and the domain name is not stored in the MySql Database. And the search in the File Manager is not powerfull enough to search the word in all files.
The PostFix smtp is also using the first domain name.

So help is needes. Where can I find the default domain name?

Best regards
Claus
