When sending email, you will make an outgoing connection to port 25 on an SMTP server. When you make the connection, you need to bind the local end of the connection to a specific IP address (corresponding to a specific interface) before connecting in order to force the OS to use a specific interface. See the Socket.Bind method for a way to do this.
