DomainKeys Identified Mail (DKIM) is an email authentication system designed to detect email spoofing. It allows organizations to take responsibility for transmitting a message, while providing a mechanism to verify that the message was not altered during transit.  DKIM uses cryptographic signatures and public-key infrastructure to verify that an email message has not been altered during transit, and that it truly came from the claimed sender. Email senders can use DKIM to sign their messages by adding a DKIM-Signature header field to the messages. Email receivers can then use the public key published in the DNS to verify the signature and check that the message has not been tampered with. 

You must first generate the public and private keys in order to publish a DKIM record. Use our free DKIM generator tool to generate the DKIM key pair.

How to publish DKIM key through DNS for eRecruiter

• Access your DNS administration interface.
• Create a TXT record in your DNS called “._domainkey” with the following format: s1._domainkey.yourdomainname.com
• The DKIM public key’s copied contents should be pasted in the part designated for the TXT record value. (The DKIM key pair needs to be generated using a DKIM key generator).
• Then click “Save.”

Once DNS settings are complete, you must give the following information to eRecruiter:

• Private key
• Domain name
• DKIM selector
• The algorithm to use (either RSA SHA256 or ED25519 SHA256)
  

Use our free DKIM record lookup tool to validate the published DKIM record.
