Nope, that ain't it. Not a new TB install. A new Dovecot install.
Same old TB I've been using to access that mailbox for years, and all
the old messages are cached - and on this current situation, there's
never been more than 20-30 new messages to go get at any give time I
start it up. Mine also only grabs the headers until such time as I
click on a message, and *then* it downloads the body. And for a 5k-10k
message, there's no reason for it to hang.

"Maximum number of connections to cache" in Advanced settings for the
server is currently set to 1. If there's another setting you're talking
about, please point me at it. :-)
And at the risk of sounding like a broken record, prior to Dovecot going
in, this thing was able to handle all my mail needs with no such
slowness on without opening new connection after new connection when I
click on another message because the one I'm on won't get past the
"downloading message..." status even though it's only 5k and going right
back to it after clicking another message gets the full display of that
message. :-)
