Dkim mail tester

DKIM (DomainKeys Identified Mail) is a technique used to authenticate the sender of an email message. Here's a brief overview of DKIM and a few popular DKIM mail testers:

What is DKIM?

DKIM is a method of verifying the authenticity of an email message by adding a digital signature to the message. The signature is generated using a private key, and the public key is published in the DNS records of the sender's domain. When an email is sent, the sender's mail server adds the digital signature to the message. The recipient's mail server can then verify the signature using the public key to ensure that the message came from the claimed sender.
