* In thunderbird, I get constant downloading of messages. Every time I
switch to the inbox from another folder, the messages start
redownloading. This sometimes, but not always, seems to create
duplicate messages, but I'm now fairly sure they are only created in the
client and not on the server. Searching through various forums, it
appears this has been a problem for Thunderbird for some time, but it
wasn't for me on Courier. As posts about similar errors seem to have
petered out over the last year without any clear guidance on how to fix
it that I could find, I expect there's a simple fix I just haven't found
yet, either in TB configuration or in Dovecot. Any hints? I tried
Thunderfix to remove the .msf files and will be redownloading my mail
over the thin pipe out to Iraq for the next 6 months (DOH!). One
artifact is that when I restart thunderbird, my inbox is reported as
having about 130 messages in it, then thunderbird starts redownloading
headers and eventually gets back up to the 1297 currently listed both in
the TB pane and by ls | wc -l in /cur. Is it possible there is a time
out that needs to be extended? In TB, I've set (among other less
apparently relevant options)
mailnews.tcptimeout;1000
mail.db.idle_limit;30000000
How old is your Thunderbird profile. Have you tried creating a new one
and see if the problem persists?
Thunderfix should not be needed by the way. Just right click on the
folder => Properties => Repair

I don't know if it makes a difference for you as you are not using
"LAYOUT=fs" but try to disable those imap_client_workarounds.
