I can ping both public address and the domain name.
Name resolution seems to be working


When trying to connect though a Thunderbird 3, no luck.

Does it work with the public IP address ? If it does, it is a name
resolution problem, otherwise it is most probably a routing or filtering
(as in firewall) issue.

Try to check if the name is resolved correctly when you ping the
hostname, as a first check.
