Rgreply Receiver When a Real Geeks Website sends an email to members they can reply to those emails, like property updates emails. And when they do those emails end up here. MailGun will send a POST with the email, where: - 'From' address is the member email, so it's our lead email - 'Recipient' address will contain the RG2 Site short id This is not treated as a lead but as an activity to an existing lead. Where the lead is identified by both Site UUID + Lead Email Address. And the activity description is the email message body.
