It’s no news to you that DKIM and SPF are the authentication protocols DMARC relies on. They provide instructions to receiving email servers on how to handle unauthenticated mail.
Now, issues with DKIM will hinder the rest of the process.
Here are 4 steps for investigating DKIM issues:
Use the DKIM Lookup tool to verify if your DKIM record and Public Key are properly implemented without any syntax or other issues.
DKIM record lookup tool checks if the DKIM record for a particular selector is published for the domain and if it is correct. It also informs whether you need to take action regarding the DKIM record validation result. To run a DKIM check, enter your domain in the Domain section, input your selector name and click on the DKIM Lookup button.
Analyze DMARC Aggregate Reports that contain all the relevant information of your DKIM Signatures (If they’re passing or failing).
DMARC Aggregate reports contain a specific tag with” selector name”, which helps you easily identify your DKIM signature Selector name. We also convert this data into an easy-to-read format where you can identify your DKIM Selector name under your dashboard’s “DKIM Auth. Results” tab.
Investigate Email Headers to retrieve DKIM-Signature, and analyze the underlying results.
DKIM selector is inserted into the DKIM-Signature email header as an s= tag when the email is sent.
DKIM-Signature: v=1; a=rsa-sha256; c=relaxed/relaxed; d=easydmarc.com; h=content-type:from:mime-version:subject:reply-to:x-feedback-id:to: list-unsubscribe; s=s1;
If you’re using third-party ESPs and obtained DKIM Public key from them, make sure you have “Activated” DKIM Signing process from their portal.
