Stop brand impersonation with Cloudflare DMARC Management

If you host your own email, and use it for things beyond just personal email, it is critical that you configure everything just right for deliverability. Since I send the Weekly Thing from thingelstad.com, I need to keep an eye on things and I've used the free version of Postmark's DMARC Monitoring for a long time. Cloudflare's new offering to do the same is impressive, and brings more data and trends. The writeup on how they built it is interesting too.
