Hello,

You can use the g_gateway setting to send messages to the sophos device 
but I assume you'd probably want surgemail to deal with actual mail 
delivery to other domains?

In which case you would also add the setting

g_gateway_ifnot "ip of sophos device"

That means everything would be sent to the sophos scanner to be checked 
but anything coming from the sophos scanner will be delivered either 
locally or send to other domains.

Described here in more detail.

Get back to me if you have any questions.

Regards,
Stuart
