You'll probably be fine. The certificates in your SMTP server are, unsurprisingly, server certificates. It is possible but not common for submission clients like Thunderbird to present client certificates rather than a username and password to log in to send mail. Postfix supports this, but if you were using it I expect you'd know about it already. https://www.postfix.org/TLS_README.html#server_vrfy_client R's, John _______________________________________________ Postfix-users mailing list -- postfix-users@postfix.org To unsubscribe send an email to postfix-users-le...@postfix.org
