Gee, "yes, we're getting your messages" would have been just as welcome a 
reply :). 

Glad to see I'm still alive here, guess it's changed a lot, I don't see the 
old names anymore.

...and I can see you did not avail yourself to the link I sent, or you would not be top posting.

It's important to understand that no one here - or on mailing lists in general - owes you anything. You must do the bulk of the work.

I know nothing about your setup, but I can make guesses immediately; It's quite possible you're using a hosted dns, and it's likely a name resolution problem.
