The latest update to everyone's favorite DMARC learning and testing tool brings an exciting enhancement: the support for multiple DKIM signatures. Now, users can view all DKIM signatures along with their respective algorithms and authentication results, enhancing the tool's comprehensiveness and utility.Have fun: learnDMARC.comPlease feel free to share it. Hopefully, this will increase DMARC...
"If email is subject to the DMARC policy of "reject", the Mail Receiver SHOULD reject the message (see Section 10.3). If the email is not subject to the "reject" policy (due to the "pct" tag), the Mail Receiver SHOULD treat the email as though the "quarantine" policy applies. This behavior allows Domain Owners to experiment with progressively stronger policies without relaxing existing policy."
"If a server isn't on the list, it's like an application being tossed out because it wasn't fully filled or the business idea is illegal."
Seriously, what?!
"DMARC establishes your policy as a sender for what should happen to your messages if they fail DKIM or SPF."
... only if they fail DKIM AND SPF (and alignment). The whole blog doesn't even talk about identifier alignment, which is a big part of DMARC.
Maybe an AI wrote the article and got stuck trying to use a weird analogy about a "competitive accelerator program" for email security? :)

It will explain how SPF, DKIM, and DMARC work together to prevent spam.
