Fix DynDNS with multiple Domain Names
I don't know if this is a problem with other DynDNS providers, but it is a problem with Namecheap. If you were to configure abc.mydomain.com, and then try to configure abc.anotherdomain.com, you will get the error:
The DynDNS mapping object with the name 'abc' already exists. This effectively prevents using more than one domain name with DynDNS.
I think this might get fixed in the next version!

Agreed, this is a nasty problem.
