forwarding to localhost


hi, I’ve been a DH user for years now and always been able to find an answer to my troubles either via Google or the Wiki. this one has my stumped.

one of my domains is using GMail for mail, and from time to time when I go to it I am forwarded instead to my local machine’s localhost. When I traceroute it traces back to DH’s email server then stops.

I understand this could be a Google issue, but wanted to check here first in case anyone had a suggestion. Thanks!
