Definitely client issue, connecting via evolution works just fine.
So I suppose it is off the the thunderbird list. I like thunderbird better.
Only plugin I use is dkim validator and when I started thunderbird w/o
extensions - still had same issue.
But I think it is definitely not a dovecot problem.

I'm not running any A/V software, and the same version of dovecot on
servers with CA signed certs (komodo) - the client connects to them just
fine.

It does look like a client issue. Do you also have some kind of AV
running? There are some AV software that can sometimes interfere with
mail sessions. See if you might be running into a similar situation:

I use dovecot on several servers. One of them uses a self-signed cert,
it's just me.
It worked fine until yesterday when I upgraded my desktop (NOT the
server) to CentOS 7.4
Now thunderbird complains when it starts up, and won't let me confirm
the security exception.
On the server the following error occurs in the log:
Sep 25 20:17:49 librelamp dovecot: imap-login: Disconnected (no auth

I believe this is a client issue, as it worked just fine in CentOS 7.3
client, but I am hoping this has been seen and fixed before.
