DMARC, just like SPF before it, solves nothing. The spammers adapt. And unlike SPF, DMARC has an enormous technology surface area. Its failure modes are legion, and each one is tedious to run down to resolution. Which just returns you to something which never pays the rent anyway.
- BenjiWiebe 2mo agoOne awesome thing that SPF/DKIM/DMARC did... Now that spammers have "adapted", it means they can't say their email is from @mybank.com, or @microsoft.com, or @facebook.com, etc!
- inigyou 2mo agoExactly. This is a very important step. The fact that it did not stop spam is irrelevant.
- Freebytes 2mo agoSPF did solve an issue. Domain impersonation is no longer as much of an issue if you are strict against SPF failures. DMARC, on the other hand, solved absolutely nothing.
