Ok. > Thunderbird isn't > supposed to be opening a new connection with each message it tries to > read; it should just read them with the one connection it has. Well, it usually uses more than one connection. I'd still try reducing the maximum number of connections it uses: https://support.mayfirst.org/wiki/speedup_thunderbird_imap > And prior to Dovecot coming into play, it did just that.

Ok, so your assumption is that some connections to Dovecot hang for an unknown reason and that's why Thunderbird creates new ones? In order to debug that, I would increase logfile verbosity für Dovecot (probably including authentication logging) and test with TB using one, two and even more connections. If this a general issue with Dovecot, TB should hang very early. >> General hint: please try to be more informative.
