Postfix : root and system user authentication
...(allowing only keypair connection), this situation provides the port 465 as another way to test passwords, for instance. I would just like to be able to implement on port 465 more or less the same requirements I have implemented on port 22, and on port 993 as well through the use of {first,last}_valid_{u,g}id : a static, and well-known set of users that are allowed to try and authenticate, even though, as you say (and I agree), that the risk is absolutely not the same as with SSH or IMAPS. So, am I to understand from your answer that the fact that login with root or with users not respecting...

Postfix : root and system user authentication
> However, when we have a postfix server on the same machine, that delegates authentication to dovecot SASL ... we can indeed log in as root on the postfix server. You are not logging into Dovecot with root, you are connecting to Postfix for submission. When you connect to dovecot using linux users (PAM) the process running takes on the UID of the login user to give file permissions to read

Postfix : root and system user authentication
Hello everyone, >From what I understand of the documentation, it is impossible to log in to the dovecot server as root, or as any user not in the interval between first_valid_uid and last_valid_uid. I have been able to verify this. However, when we have a postfix server on the same machine, that delegates authentication to dovecot SASL according to the configuration described at https://doc.dovecot.org/configuration_manual/howto/postfix_and_dovecot_sasl/, we can in...

I am sure that we need...
