The problem is solved, though for a rather silly reason IMO. :-)
Now, to reprise - the problem was with Thunderbird and messages which
were showing bold in the message list (I.E. were flagged as unread).
Clicking on the message caused things to hang. If I clicked off of the
bold message, it would then switch to non-bold (read), and the Dovecot
log would show another connection being established with an additional
login. Returning to the newly-read message displayed the message just
fine. This was happening consistently with my Windows desktop system.
Well, over the course of last weekend, I was traveling and used my
laptop, which also uses Thunderbird. It worked without a hitch. No
problems, no hangups, it worked exactly as it should have.
I realized at that point that the *only* difference between the two is
that since the laptop travels, I've always had it configured to connect
on port 993 and encrypt the connection (SSL/TLS). Whereas the desktop,
being on the home network and not needing so much protection, was
connecting to port 143 and was not using any encryption at all. The
minute I changed TB to go the encrypted, port 993 route, the problem
magically went away there as well! I have NO idea why an unencrypted
port 143 connection caused that weird problem (as I said before, the
previous IMAP server I had been using did not cause this issue). And
frankly, at this point, I don't *care*. <grin> I'm just happy the
flipping thing is working now. :-)
Thanks to all those who had suggestions to help out with this!
