Hi, basically this is how it could work, but it isn't something I have done for a while now and never use myself, but here goes.
You must have NAT installed and active to do this.
In GateKeeper, disable the POP3 and SMTP servers [or changing them to another vacant port could possibly work].
In each client, configure for a direct connection to the POP3 Server / SMTP Server of the host / ISP / company.
Antiviral filtering won't apply in this connection model.
Oh and upgrade to V6.1.1 is a must, your current licence will provide the same functions as 5.x with all the benefits of 6.x.
