Hello,
I'm using Dovecot 2.2, Postfix 3.5, and am atempting to get the latest version of Thunderbird to work. I tried account autoconfig which did not work, so I had to manually enter information and correct other information. On my server dovecot supports plane and login authentication methods but only over starttls i've got a letsencrypt certificate. My thunderbird configuration looks good, right hosts for incoming and outgoing mail, right ports, 143 starttls, and 587 smtp submission, and thunderbird has the authentication method set for normal password. This I interpreted to mean thunderbird is going to starttls then send the username and password. Thunderbird is giving me this error:
imap server does not support the selected authentication method
I realize this is vague, any suggestions?
Thanks. Dave.
