| Dec 6, 2016 at 20:19 | comment | added | G Bagoy | Probably I was not clear. I am talking about outgoing email, not incoming. I need to accept incoming email, that is not a problem. I do not want local processes to be able to send email directly, without using my postfix, and I don't want local processes to be able to send email through postfix without authentication. | |
