SPF, DKIM, and DMARC Simplified

SPF, DKIM, and DMARC Simplified

For a 6-minute sweeping overview on the three main security standards that help stop email phishing, spam, and help increase deliverability, this video from The InfoSec Academy is about as quick, yet thorough, as it gets.

It may leave you with more questions about SPF, DKIM, or DMARC, but that’s a good thing.

I’ve worked for big and small organizations and am routinely surprised that no one has set these up on their email system. When I tell them they don’t have it setup (or setup correctly), it’s rare that even the I.T. Department knows what I’m saying. Often, I just get ignored: “Well, you got the email, didn’t you?”.

To me, SPF and DKIM are as important as fire extinguishers in a manufacturing facility. Don’t worry that there were no fires today; instead worry there may be one tomorrow and all these materials in this building will be a liability.

Email is similar. It’s very powerful. If you’re sending outbound email as a company, you need to think about consulting with someone. You need to setup your mail server and email domain correctly, otherwise, what are you doing?
