    Hmm, kind of although slightly different - I think...

    What I need to be able to do is have one set of users only be able to email a certain domain (a company partner) an no other addresses (i.e. their mates)  Everyone else should be unaffected.

    The solution you posted seems to be the other way around.  I.e have the domain and restrict who can send to it...

    I would say, this is exactly the same.

    Setup a connector, put in "" as adressspace, your virtual SMTP service as Bridgehead and there you have also the option to allow or deny users on the recipient filter tab. Restart the services after you changed the settings.

    You can setup
    Deny all but allow a few users
    Allow all, but deny a few users

    Works a treat, but need to add a registry key as descibed to enable restriction checking.
