Well, this does indicate that smtp and smtps are listening on all
interfaces.  So, the fact that you are getting "connection refused" outside
of the box but can connect inside of the box does indicate that even though
you think your iptables firewall is off...it really isn't.  If you have
logging turned on for iptables you should see messages in the messages log
on /var/log.
