All emails generated from within Jackrabbit display your organization name (Tools > Edit Settings > Organization Defaults) in the From field. Emails sent from your Jackrabbit database must be sent with an email address from the Jackrabbit domain. This is due to DMARC which is an email protocol that requires authentication of the sending email address. Emails that are not authenticated are at risk of being undelivered. To ensure that your customers receive, and are able to reply to, your emails Jackrabbit sends the message from 'firstname.lastname@example.org'. Our Developers have created code so that your customers are able to reply to these emails and you will receive them in the inbox that you designate when you create the email in Jackrabbit.
