??? * CVE-2019-3814: If imap/pop3/managesieve/submission client has
??? ? trusted certificate with missing username field
??? ? (ssl_cert_username_field), under some configurations Dovecot
??? ? mistakenly trusts the username provided via authentication instead
??? ? of failing.
??? * ssl_cert_username_field setting was ignored with external SMTP AUTH,
??? ? because none of the MTAs (Postfix, Exim) currently send the
??? ? cert_username field. This may have allowed users with trusted
??? ? certificate to specify any username in the authentication. This bug
??? ? didn't affect Dovecot's Submission service.
