We are encountering errors with several domains similar to the one
reported by samba.org:

This is causing us problems in our operational departments.  Based on
the message traffic surrounding this issue I have changed the client

smtpd_tls_ask_ccert = no.

Any insightful comments on this situation are welcomed.
