You need to make a connector with permissions for relay to that IP address to enable the relay.

We usually make a separate SMTP server on IIS if there's a server or IP address handy or you could use a custom port or socket to relay the message.

You could also find out if your ISP supplies an SMTP server and tell the other device to use that.
