Have you tried creating a new account with the same settings as the normal Dovecot account? Maybe Icedove/Thunderbird has corrupted some local data.
I moved the entire directory out of mozilla-thunderbird, deleted the account, and then created a new one. Performance is now even worse. There are few things that I can do without triggering a crash. At the moment I'm using Squirrelmail, since there's something wrong with KDE: KMail now fails to start.
If it persists, then get a raw log from Dovecot and let's see what has to be done from there.
Let's do that. I need a pointer or two. I assume that protocols = imap is equivalent to protocol { ...imap }. Is this correct? I shall try it and see what happens, but I don't want to make things worse.
Thanks
Cam
