    Default How to restrict sending mails


    I want my users not to be able to send mails from untrusted networks even when they are using passwords.
    So when someoane from outside my local LAN sends a email it will be rejected unles it is for my local domain.
    Can I do this?

    Thank you

    1) Use milter - The mail filtering tool and parse the HTTP request header OR mail header to get origin. 2) DO NOT allow login from out side of network.
