    in mail server, make sure authenticated users are allowed to relay

    make sure your client uses authentication and right password.

    something that can be fun to do is telnetting port 25 and authenticating manually :p that is how I made sure the auth works

    launch mailenable admin and find the smpt and look at its properties, in the relay tab, allow authenticated servers to relay

    ahhh sender address must be from a local post office box

    1. to localhost to dispatch an existing mailadresse must be present. allow authenticated servers to relay is not sufficient. except you can indicate username and password.
    2. the receipt smtp server does not find the mail adress on your mailserver (can be a spam)
