Hello, I started a mail server where I manipulate incoming messages through a script. This is 100% working.
But my "backend" (postfix configuration) is very basic. I am now implementing basic security, trying to understand how postfix works and everything. First of all, I am trying to reject messages to users that I have created, not to root/apache/mysql or something only for the system. I tried to configure aliases. It works, but does not reject system users. Then I tried to configure access file, rejecting messages to root/apache/mysql. It worked well, but I am not sure about this is the better way. Even because I dont know if add users to a "unauthorized users" is better than add "authorized users". Is there a way to create a list with authorized users to receive emails and all the others -- in the /etc/passwd -- dont?
