I could not find any option I could set in the dovecot.conf or the
sendmail.mc file to make libssl accept tls 1.1.  I managed to revert
back libssl to get back to a working situation until the client's get
updated.

I downloaded libssl1.1_1.1.0f-3_amd64.deb

and did:

dpkg -i libssl1.1_1.1.0f-3_amd64.deb

restarted sendmail and dovecot and everyone can now connect.
