Hello, I have mail_version = 2.8.3 on CentOS 5.7 (x86_64). Everything is running OK; the server only accepts local or authorized (using STARTTLS) connections, as there is another mail gateway receiving/filtering and delivering locally to this one. STARTTLS is configured and works fine. In

Sending smtp-authed mail to policyd?

I noticed this the other day when debugging a self-inflicted issue with postfix and LDAP. If postfix is configured to bind as user X, and user X doesn't exist in LDAP, LDAP will return error code 49 (invalid credentials). This is of course the correct behavior on the LDAP side of things.
