No errors. Configuration looks fine.
I am trying to reproduce. Removed the maibox in Thunderbird and recreating it did not make a difference. So it looks related to Dovecot as well.
Notifications start to work again if I leave Thunderbird running, restart Dovecot, send a couple of mails to the account, click on INBOX so they show and delete those e-mails. Next new e-mail arriving shows the notification and all e-mail afterwards as well until I restart Thunderbird.
