The option to override the reply to allows you to redirect all replies for that email send to 1 particular user email address.  You will want to use this with caution as generally, you will want your replies to go directly back to the sender instead of sending the recipient to another source.

By default you want this setting to remain Market From, which will keep the original sender as the 'reply to' as well.
