Okay, well after entirely too much excitement, I made some progress. After much googling, I found that this error message refers to a problem with GNOME so one can get around it by going into console mode, which I did with alt-shift-F3. I then was able to edit the config file and worked out that the problem was that contrary to the appearance of the example commands, the line starting with "default-priority" needs to all be on one line. After I made that change, I was able to reboot back into GNOME. With the security level lowered, the GNOME Online function of the Settings app now worked! I am now fully able to get e-mail from this account. Given how fraught this all was, may I suggest that someone address this issue?
