that's exactly what we want!
I tried installing it today but it kept stopping services and needed SQL installing so I've left it for another day. Is it easy to install? It was asking for IP addresses of incoming / outgoing mail but i'm not sure what these were
Sorry won't be much help now, it's been installed so long I can't remember how I set it up. I don't recall any difficulties, Sophos support are normally pretty good - give them a ring :-)
