Okay, after doing some tests I can confirm the same behaviour. I set up the old thunderbird-librnp-rnp-91.12.0-1.fc36.x86_64 to access my local IMAP server, and it worked well (in the manner I'm used to seeing it behave). I updated to thunderbird-librnp-rnp-102.2.0-1.fc36 (and everything else currently available to update) and it jams trying to view any email in the cache, with a message "Checking mail server capabilities" in its status bar, and pegging the CPU close to 100%. If I move to a different folder, one that I've not cached anything from before, it sits there sulking doing nothing, and the CPU load goes down to 10% (or similar) after a few moments. A quick look at my /var/log/maillog files shows masses of errors just like this: Aug 29 00:00:54 rocky dovecot: imap-login: Disconnected (no auth attempts in 0 secs): user=<>, rip=192.168.1.2, lip=192.168.1.1, TLS: SSL_read() failed: error:14094412:SSL routines:ssl3_read_bytes:sslv3 alert bad certificate: SSL alert number 42, session=<HuOl/k3nFOLAqAEC> The last bit with session=<> has different data between the pointy brackets for each log entry. Of course it could be that it doesn't like my self-produced certificate, but my server is set up to only allow secure access, so I can't see if Thunderbird works without SSL. It's after midnight, and I'll leave it to tomorrow to try anything further. For what it's worth, running Thunderbird from the command line sheds no information beyond these four lines as it starts up: ATTENTION: default value of option mesa_glthread overridden by environment.
