Ok, let me ask the administrator first. I appreciate your help Andy.

Well, that's where your problem lies - your local IT environment is 
blocking connections to external SMTP mail relays.

It's listening on localhost (127.0.0.1:25) which is normal as you usually 
want sendmail to accept system messages, etc and deliver them to local
users. But it cannot make connections to external hosts listening on port 
25 except those defined by your network administrator.

Although all this is way off-topic for Maui, let me know off-list if you 
know the name or address of the SMTP relay you are expected to use and you 
want help configuring your sendmail to use it.
