Also, for some more details on how all this works together, check out this presentation I gave a couple of years ago. I wrote a quick script to do all that automatically, to the point where it can be thrown in a cron job without even thinking about it. If you manage a lot of domains, that can be a pain to do. Don’t forget to make those changes to your DNS records!ĭKIM, however, requires periodic key rotation. Once you get SPF and DMARC set up, you can pretty much set those and forget them unless you make changes to your outbound email infrastructure. Remote servers can choose to ignore this policy, but most will follow your lead.

DMARC is the enforcement leg of the tripod and tells remote servers how to handle emails that fail SPF or DKIM checks.Headers typically signed are From, To, Subject, and Date. DKIM creates a digital signature on some of your email headers so receiving servers can cryptographically authenticate those headers as valid and original.Meaning, if an email from your domain comes from, and you didn’t specifically authorize as someone who can send email from your domain, look at that email suspiciously. SPF allows domain owners to define the valid mail servers authorized to distribute their email.Here’s a quick review of what these three frameworks are and how they work together:

With a few tools, some I wrote, it turns out to be pretty simple! Given that I’m running this individually, I wanted to see how hard it was to set up and manage. I started experimenting with these years ago noting that there are several vendors who will happily do this for you-and by the way, their products are pretty awesome. Perhaps it was word choice, perhaps you ended up on a list somewhere, or perhaps you are not doing your part to elevate the confidence of your emails leveraging the tripod of email security frameworks known as Sender Policy Framework (SPF), DomainKeys Identified Mail (DKIM), and Domain-based Message Authentication, Reporting, and Conformance (DMARC).

If some kind of syntax or evaluation error occurs (eg. If a domain has a temporary error during DNS processing, you get the result "TempError" (called "error" in earlier drafts). If a domain has no SPF record at all, the result is "None". If no mechanism or modifier matches, the default result is "Neutral".
