So at my dayjob we have a pretty good amount of domain names we've registered for brand protection or typo domains. 3 domains we send or receive emails on, and 23 domains that just forward to a URL on our main domain. Our customer care got word of someone sending scam emails on one of the brand protection domains that should never be sending emails.
Let's explore how I setup our parked domains to report spoofers to me and help other mail servers know they shouldn't trust these emails pretending to be us.
