What is a DKIM record?
Posted: Sat Feb 01, 2025 9:32 am
A DKIM record refers to the public key of the electronic signature attached to an email and the associated information that is registered in DNS. The sender of the email signs the email using the DKIM mentioned above. The recipient of the email retrieves the DKIM record from the DNS of the email sender domain and verifies the DKIM signature using that public key. The DKIM record is information necessary for the recipient of the email to verify the electronic signature, so it is necessary to register the information specified by the email delivery system.
In addition, electronic signatures can be medical practice email list successfully verified if the private key and public key are a correct pair. Signature verification allows you to confirm that the email was sent from the sending domain (i.e., it was not spoofed) and that the body of the email has not been tampered with.
What is DNS? MX RECORD explained
In email delivery, not only the visible parts (design and text) but also the invisible "reliability of the sender (server, etc.)" is important. We will explain the "DNS mechanism" that you need to know to take measures for that "invisible reliability", as well as "A RECORD", "MX RECORD", and "TXT RECORD" that are closely related to email delivery.

What is sending domain authentication?
As mentioned above, "DKIM" is a technology that authenticates the sender domain as a legitimate sender and prevents spoofing of emails. This type of technology is called "sender domain authentication."
In addition to DKIM, which we will introduce here, there are other "sender authentication" methods such as "SPF" and "DMARC." We will explain the differences later, but all of them are technologies that use some mechanism to authenticate whether a sent email is from a legitimate sender and to determine whether the email has been spoofed. Sender authentication plays an important role in preventing unauthorized email sending, such as spam emails and phishing scams.
It also allows the recipient to verify that the email is from a legitimate sender, helping to avoid security issues.
How DKIM digital signatures work
A feature of DKIM's "sender authentication" is the addition of an electronic signature to outgoing emails.
