Domainkeys identified mail gmail

A blast from the past!

DomainKeys Identified Mail (DKIM) is a method for authenticating the sender of an email message. It was introduced in 2007 by Yahoo! and was later adopted by other email providers, including Google.

DKIM uses a digital signature to verify that an email message comes from a specific domain. The signature is generated using a private key, which is stored on the domain's DNS server. When an email is sent, the sender's email server uses the private key to generate a digital signature, which is then included in the email message.

When the email is received, the recipient's email server can verify the digital signature using the public key, which is also stored on the domain's DNS server. If the signature is valid, it confirms that the email message came from the specified domain and has not been tampered with during transmission.

Gmail, which is a service provided by Google, supports DKIM authentication. When you send an email from a Gmail account, Gmail generates a DKIM signature using a private key that is stored on Google's DNS server. The signature is then included in the email message.

Here's how DKIM works in Gmail:

  1. When you send an email from a Gmail account, Gmail generates a DKIM signature using a private key that is stored on Google's DNS server.
  2. The DKIM signature is included in the email message, along with other headers such as the "From" and "Subject" headers.
  3. When the email is received by the recipient's email server, the server can verify the DKIM signature using the public key, which is also stored on Google's DNS server.
  4. If the signature is valid, it confirms that the email message came from a Gmail account and has not been tampered with during transmission.

DKIM is an important security feature that helps to prevent email spoofing and phishing attacks. It ensures that email messages are authentic and trustworthy, which helps to build trust between senders and recipients.
