Have a look at IronPort (http://www.ironport.com/).

I think this is not possible with this appliance right now. But I am
sure, that IronPort can (and will) implement this if requested.

Ok.

Ok. (SOPHOS) (and others in upcoming releases)

Yes. More granular privilege levels in next release (IIRC).

You can create different policies for different users. You can apply
these policies to users using attributes stored in a LDAP (or you can
have static mappings on the appliance itself of course).
