That is impossible with assp. At the time you connect to the proxy, you loose the original target, as this is not included in the Data of the traffic.
It could be possible to redirect all Port 25 traffic to ASSP on your router. But how would the Proxy know the original adress? So you need a product, that analyses the traffic on the network layer, proxy it until the mail is send and forward it to the original server. I don't know any such product. Why don't you forward all port 25 traffic from your Network to ASSP and hen with your own mailserver to the end user, regardless of the settings of your clients? > Hopefully the former.
