From a friend:
As you noted, changing the nameserver delegation is unrelated to the
mail issues you may be having. When attempting to communicate with your
server via Telnet on port 25, it simply hangs and does not provide a 220
SMTP header acknowledging the connection and readiness to receive
commands. You will need to check the server configuration to determine
why it is not responding properly.
I am getting extremely cross now as i am starting to look like a fool!
