DMARC is nice though. It won't stop spam. It won't stop spoofing. But you will know that someone somewhere is spamming people using your domain name. How awesome. :)
- toast0 2y agoI never found the DMARC reports actionable, so I quickly turned them off. What do you do with the information? Of course, even with hard fail spf and dmarc, I still see some bounces from spam where some server accepted the mail to deliver it elsewhere and the next server denies it, so the first server sends me a bounce.
- riobard 2y agoDMARC reports are for you to be sure that you configured SPF/DKIM correctly, not asking you to do something with the spoofing senders (which you can do absolutely nothing about).
- toast0 2y agoYeah, so have reports when you start, but once you get things set up correctly, turn off the reports. If you break things later, you should find out quickly when mail is refused, and you can turn on reports again, if you need to.
