My email woes are over, at least for now. I managed to get Thunderbird working again, and everything is now fine... well, aside from the fact that I am about three thousand emails behind, but that's the usual state of affairs.
Thanks to everyone who commented or emailed or otherwise offered help. I appreciate all your suggestions.
I will be taking steps next week to make certain the problem does not recur.
