Answer 1

Your outgoing connections to port 25 may be blocked (firewalled) to prevent outgoing spam.

Do you get smtp greeting message when you te.net smtp port on the host from command line?

telnet hostname.domainname 25

Does the smtp server handle MSP (587) port? [port for message submission via smtp protocol]
