Thank you for the effort. So there's nothing obviously wrong with the

My intuition is that placing my wife's domain name in here would do no
harm. I tried adding it, sent a test message to the machine, and clicked 
on "Get Mail". But result ambiguous. 

The machine had automatically downloaded some messages from earlier this
morning. I sent a test message after changing the above configuration. When
I clicked Get Mail it acted reasonably quickly and retrieved my test
message without generating an ERROR message about connection. However, this
turned out to be a fluke.  A subsequent test message sent to the machine
was not automatically downloaded, and "Get Mail" again generates connection

No. As you suspect, a typo.

I'm not sure what "random" DNS means. I put the scipt on the machine and
ran it. It returned an IP address for mail.omnis.com. Is the idea that the
script checks every five minutes and I should look for changes in the IP
address? I tried to run it on my own machine to compare results and for
some reason get permission denied.
