Description

User Agent: Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/41.0.2272.76 Safari/537.36

Steps to reproduce:

Tried to receive mail from the IMAP server imap.robots.org.uk


Actual results:

Frontend says "The IMAP server {account name} does not support the selected authentication method. Please change the 'Authentication method' in the 'Account Settings | Server settings'."

According to the IMAP server logs:

    Apr  5 13:50:43 traxus dovecot: imap-login: Disconnected (no auth attempts in 2 secs): user=<>, rip=192.0.2.1, lip=37.139.10.94, TLS: SSL_read() failed: error:14094412:SSL routines:SSL3_READ_BYTES:sslv3 alert bad certificate: SSL alert number 42, session=<jEq6d/oSiQBWDzs8>

It looks like Thunderbird is rejecting the server's certificate, but it doesn't actually tell the end user this, nor does it log it in the error console.

The certificate is fine, at least it used to work until today, and still works with mutt, Evolution and K9.


Expected results:

Connection to IMAP server should have worked.
