    Of course Fred Avolio's last statement on the subject really
    gets to the heart of the matter: first define your policy, then
    check if the desired application is in compliance with it.

    But there should be a quick technical solution, if I understand
    your setup correctly - you already run an internal mail server
    that is protected by the firewall, right?

    Why not have the cellphone users use the mail server as a smarthost
    if they are "internal" to your network? If they are "external", i.e.
    connected to an arbitrary ISP, they should use that ISP's mail
    server for relaying anyway.
