One possibility: SMTP servers are often configured to reject connections
from networks or hosts they don't know. They also usually reject mail that
is not from a trusted host or network, or not addressed to a host or domain
the mail server accepts mail for. Mail servers that accept mail from
anywhere and send mail to anywhere are called open relays, and they are
considered a bad thing because spammers use them.

If you get this far the SMTP server is accepting your connection. If you
don't get this far you'll have to talk to your mail server administrator to
see if they can open the mail server up for you to use from outside.
