When you enable mail_debug, is there something in the logs?

Does it work if you just kill -HUP dovecot?

Try to lower the number of simultaenous connections Thunderbird may use. 
This has the same effect, eventually.

Is the mailbox pretty large? thousands of Mails or >= 2GB in size? 
Thunderbird does not like those ones.

We had an user with a similiar effect. It was a years-old profile 
(probably even converted from a Netscape 4 profile years back). When I 
re-created the profile, just copied the bookmarks file and re-imported the 
addressbooks, the problem was not seen again.

How many users are working on your server?

Bye.
