The certificate I got is for "mail.<domain>.com" which should be correct.
My MX record redirects to "mail.<domain>.com" while I also have an A
record with a prefix "mail" which redirects to the correct IP. But
Thunderbird sees the Location as "imap.<domain>.com" opposed to the
"mail." address I made the certificate for.
I have not used it in a few years but I do support some users of it and to
the best of my knowledge Thunderbird does not invent names at random, it uses
the server names YOU configure it to use.
That's not totally true. If no autoconfig is configured for the domain and
you have a catchall entry pointing to your server, then you will get
imap.domain.tld and smtp.domain.tld as servers. As the IP is correct and
the server reachable Thunderbirds autoconfig stops there. Either setup
autoconfig for your domain or enter the correct server names in the
Thunderbird setup dialog after the autodetect is done.
