I'm using AM Forms on a site that I've built. The site is now in production.
Am I correct in thinking that these notifications are being sent via Craft's email settings (currently PHP Mail)?
G Suite is running DKIM, SPF and DMARC, so the PHP Mail protocol is not the best method for receiving these notifications. If I change Craft's email protocol to GMail, how safe are the credentials I enter and are they encrypted?
