your DKIM keys might be stuck in 2015

our free DKIM checker tells you the key length and algorithm in one lookup

but here's the thing: a passing check today doesn't mean you're safe tomorrow

keys should rotate every 6-12 months, and anything under 2048-bit RSA is living on borrowed time

DMARCguard monitoring tracks rotation gaps, flags weak keys, and alerts you when a selector goes stale

Look up DKIM public keys by selector, verify key sizes against RFC 8301, and check algorithm compliance.

Gelten die Regeln nur für Firmen-Emails?

Und wie wäre es, wenn man prüft, ob der Absender wirklich derjenige ist, der er vorgibt zu sein? Also DKIM-Check? Geht mit Thunderbird-Erweiterung automatisch und steht dann gleich unter dem Absendernamen.

DMARC has changed, so I updated the LearnDMARC quiz to match the new RFCs.

Think you still know DMARC inside out?

I challenge every email authentication nerd, deliverability specialist, postmaster, DNS wrangler, and DMARC report parser builder to take the full 42-question quiz and see how RFC-ready you really are.

If you can ace them all, you’re an absolute DMARC nerd. And even if you don’t get every answer right, I guarantee you’ll learn something.

The quiz was desktop-only until now, but after 816 people started it today, I decided to make it available on mobile too.

Take the full quiz:

Let me know your score, and challenge your colleagues by tagging them in the comments. Bonus points if you find a question that made you doubt yourself.

I am surprised at the number of organizations that are staunchly opposed to #SPF and #DKIM. They won't even do simple research into what they are. I have gotten the most push back from government organizations. The bad actors have the greatest compliance rates. This is why we can't have nice things.
