Can you pint that host? "No route to host" generally indicates you cannot
even ping an address, due to having no connection to it. What happens when
you telnet to a known mail server. For example,
> telnet mail.neilschelly.com 25
That should work and if it doesn't, it's GoDaddy.

It doesn't appear that anything is being blocked outgoing and all incoming
packets that are part of a locally-generated connection are allowed, so
iptables isn't interfering.
