It indeed works for me to date. I don't know if I should be scared of it
now that you are saying that this breaks with latest windows update :)
One thing I could thing of - There might be problem with ciphers. I also
messed around with it. Check the https://www.immuniweb.com/ssl/ test
(put your.mail.server:993 as address) to see how it likes you ssl
implementation.
Other solution would be to run nginx as a proxy (which I also did).
Nginx needs auth module to authenticate and choose which back end has
emails for this specific user. It is a simple script what will connect
to qmail mysql server and check for user and password fields. Could be
in perl, python or even bash/command line. I wrote this also (in PHP). I
was thinking to use this as moving over per domain or email for testing.
Made the solution and used it for my email accounts but never got around
finishing the plan and converting to dovecot.

I do have another server which was upgraded to dovecot , but you need to
pay attention to prefix = INBOX. parameter if you are coming from
courier. It needs to be set, otherwise outlook will act wierdly and wil
not sync mail anymore (thunderbird understands the change and works
automatically). I think it's documented in conversion tutorial. And
indeed if there would be problems then I would know as there are most
users running outlook on this server (around 100 accounts).
IMHO dovecot is MUCH faster with mailboxes with alot of emails in one
folder.

I think this would indicate that our Dovecot IMAP supports TLSv1.2

FWIW, I applied Janno Sannik's patch
<https://www.mail-archive.com/[email protected]/msg43073.html>
to enable TLS 1.2 in Courier 4.1, after which testssl.sh reported that
TLS 1.2 is working correctly. However, some of our users still
reported errors using Outlook. So, the issue doesn't seem to be as
simple as enabling TLS 1.2?
I'm currently working to replace Courier with Dovecot, since you
mentioned the latest Dovecot version works for you.
