Introduction<\/b><\/h2>\n

Email authentication is important in the digital arena as it protects sensitive data. One of these protective measures is Domain Keys Identified Mail (DKIM). It’s vital in achieving full DMARC record compliance. Therefore, this failure may lead to harmful activities like phishing, spoofing, and intermediary attacks.<\/span><\/p>\n

Basically, DKIM checks email correctness using cryptographic signatures. So, it confirms that an email input comes from the declared sender domain. The protocol averts email spoofing and forgery attempts, including harmful links, leaking secure information, or distributing malware.<\/span><\/p>\n

This document discusses what happens when DKIM fails and provides solutions for DKIM-related problems.<\/span><\/p>\n

What is DKIM?<\/b><\/h2>\n

\"Error<\/p>\n

DKIM is an email verification tool. It allows received mail servers to confirm if incoming mail is legitimate for the sender domain. Additionally, with each outgoing email sent, DKIM attaches a cryptographic signature. This lets the receiving server validate and approve the transmitted email.<\/span><\/p>\n

In certain situations, an error ensues when the receiving server cannot identify whether the DKIM signature isn’t valid, outdated, or missing in public DNS domain records.<\/span><\/p>\n

What Constitutes a 550 DKIM Verification Error?<\/b><\/h2>\n

A 550\u00a0 verification <\/a><\/strong>error alert occurs when external services for DKIM validation state that the scenario is invalid<\/strong> because the public key isn’t accessible after a DNS lookup.<\/span><\/p>\n

The problem also occurs when the public DKIM key and the private key on the sender’s email server conflict. Regardless of the reasons leading up to this kind of error, our support team has simplified solutions ready at its disposal.<\/span><\/p>\n

Reasons behind DMARC failures<\/b><\/h2>\n

Sometimes, DMARC verifications fail, exposing emails to potential risks. In this part, we’ll discuss the known reasons for these DMARC errors.<\/span><\/p>\n

Out of 1.5 billion domains that returned an answer to our DNS query, we found that ~32% of domains had an SPF record<\/strong><\/a><\/p><\/blockquote>\n

Syntax problems<\/span><\/h3>\n

DKIM record is text-based, and even a single mistake can cause misconfiguration. So, to avoid such problems, the best preventive measure is to use a reliable record generator.<\/span><\/p>\n

DKIM Signature Does Not Align<\/span><\/h3>\n

The problem occurs when the “From” header “email” does not match the domain in the DKIM signature. So, you have three alignment choices available: strict, relaxed, or none at all.<\/span><\/p>\n

A few reasons can cause failure:<\/span><\/p>\n
