Configure at least 3 SMTP ports for Domino

Recent Internet providers are OP25B and cannot connect to port 25.

Domino allows you to set up additional ports for SSL, but you can only set up to two ports for SMTP, and you cannot use port 25, 465, and a submission port (587) together.

Similar ideas have been submitted for this, but I would like to be able to have more than 3 settings for SMTP.

    Ultimately, we want 25 to be unauthenticated and 587 to be authenticated.

    Therefore, we believe that FW port forwarding will not suffice.

    You could configure your firewall/router to do a port mapping
    Using a configuration like Router:587 => Domino:25
    would that work?
