The only way this might be Dovecot's fault is if STATUS commands don't  
see the new mail. For example:

a STATUS mailboxname (MESSAGES UNSEEN)

If running that command sees updated values, the problem is with  
Thunderbird which probably doesn't even try to send that command then.  
I don't really know if TB normally does that or not, most other  
clients do anyway.
