Thanks for your reply. Yes, the ports match
and are both 9989.
The second problem is definitely a firewall issue:
our firewall simply won't permit traffic out on that
port. I will move the master to 80 and see what
But I think the first problem is different: I'm
guessing it's the interface between the Twisted
mail.smtp library and sendmail. Or am I missing
