Interesting suggestion Nick. But I think I have found an easier one, albeit one that requires a hardware change and different service here.

I talked to Comcast Business this morning and can get a static IP, 600 Mb service (not guaranteed of course) and access to port 25 if needed. My SMTP2GO contact noted that my current Comcast dynamic IP address is blacklisted with two major services, due to ComCast's block assignment, and I can't get that lifted. He speculates that the blacklist was what might be causing ComCast, who provides the IP, to disallow a connect. Seem logical, although it does bring the chicken or the egg, or perhaps Catch 22 into the equation.

Anyway, the ComCast gentleman is investigating whether getting emails to a static address with them will be an issue. If I move to that service, drop Lumos altogether, the net cost is almost the same, so I expect, once the mail situation is confirmed, that I will do just that. Their business max service also provides an LTE 4G automatic backup with two different cell providers, so the need for the Lumos DSL backup goes away as well.

There will be some work involved in removing all references to the ntelos.net email address, but I know most, if not all of the location that I have used it either as a logon or a return email address, so once all that is changed over, I can dump Lumos without much regret. It's not the same service I moved to from Verizon more than 20 years ago.

I do appreciate the time you've spent in trying to help me with this problem. If nothing else, I've learned a great deal and expect that this solution is going to work, and stop the outages altogether.
