When a guest, producer or audience member replies to an email, where does it go?

When a guest or producer replies to an email sent from Riverside about any scheduled session, their reply goes directly to the inbox of the host. 

When someone registered for a webinar replies to a webinar registration email from Riverside, their reply goes directly to the inbox of the person who created the webinar. If a custom Reply-to email is set for the webinar, the reply goes to that address instead.
