Your "sendEmail" software is not configured to trust the certificate
of this Postfix server.

The problem is not with Postfix. It is a configuration issue with
"sendEmail". It needs to be configured to either not check the
SMTP server's certificate, or trust whichever CA signed the Postfix
server's certificate.
You can also obtain a DV certificate from one of the usual suspects,
and sweep the trust management problem under the rug (the DV CA
will make an unauthenticated email delivery to ad...@example.com
to confirm authorization to issue an example.com certificate).
