We host a domain 'nabina.com' with brinkster.com and use the same to provide us with emails to all our staff. The 'Servie Provider' provides facility to capture the incoming emails to another account. My concern is the email that our staff send from the individual Pc's in the workgroup/domain which I need to monitor and filter anly selected email. I would like to mention an example the emails that our sales staff send to suppliers must be blocked while to the cutomers should be allowed. Additional features to the device is welcome.
