Hallo, I would to like to enable SMTP authentication, as an option feature for our users, but I have some questions before doing so. 1st: Is it possible to enable it, without Cyrus of Dovecot? I do not want to install Cyrus of Dovecot on my gateway. 2nd: As far as I understand, there is an option to use SMTP auth for mail submission only. Right?
Thanks, Peter
