We need to send emails from an application in a server that it is not connected to the internet or any other network. The network of this server is 192.168.0.0 /24 (first network card). This server has another network card. We thougth of configuring the second network card and connect it to a network (10.140.0.0/24) that has a path to send emails. The 10.140.0.0/24 network does not route 192.168.0.0/24 and we can't change it. By configuring the second network card can the application send emails through the second network? can this work?
