Thank you for this. I am not using self-signed, I am using letsencrypt
as a CA, the certs are installed where certbot put them.
I tried the example from https://wiki2.dovecot.org/TestInstallation,
using openssl s_client, and I achieved the following (lots of data
replaced with "...")
I have not changed anything else since your last reply, I am honestly
not sure what rc config has to do with certs (google has not given me a
result that seems to apply). Does the below help confirm my certs are
properly installed and that i can connect to dovecot over tls and pass
my credentials?

i don't understand why it can't connect, this seems to work fine:
fine ?
you're manually overriding at least one problem with your certs/config
...
- Status: The certificate is NOT trusted. The name in the certificate
does not match the expected.
*** PKI verification of server certificate failed...
Host 10.0.0.91 (sieve) has never been contacted before.
Its certificate is valid for 10.0.0.91.
Are you sure you want to trust it? (y/N): y
...
it appears that you're using a self-signed cert? are your trusted
certs defined and correctly chained? if not explicitly defined, did
you correctly add you certs to system ssl dirs, and ensure hashes are
correct?
demonstrate first that you can connect to dovecot over tls with a cmd
line client, without ignoring or overriding your cert problems
including any client/server cert verification requirements you've
turned on in dovecot config
once you've passed the correct certs, then demonstrate that you can
authenticate in the same session with any password/credentials you've
set
once that all works, make sure you've got those certs correctly set up
in your rc config
