Hello 10_ray,
Thanks for the question about setting up a forwarder from a specific sender. Actually, this would be an email filter. Click on the following link to learn how to create an email filter. Basically, you set a condition (i.e. the email address) and then set an action. When the condition for the filter is met, then the action (forwarding the email) is automatically processed.
I hope that helps to answer your question! If you require further assistance please let us know!
Regards,
Arnel C.
