I can see that virtualmin create a NS record wit hostname value for all created domains ! But I think this is wrong.
I've configured virtualmin wizard to use : ns1.mydomain.com ns2.mydomain.com as the nameservers and they're all set. my hostname is : sv.mydomain.com
Why virtualmin creates a NS record for sv.mydomain.com in all dns records ? I'm getting error from http://intodns.com/ when I check my dns records validty.
This just fix when I use ns1.mydomain.com as the hostname which doesn't make sense at all !
