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. 

Once you have the DKIM key pair, you must publish the DKIM public key through your DNS while Freshservice uses the private key to employ digital signatures for your outgoing emails. Take these steps to publish the DKIM key:

How to publish DKIM keys through DNS for Freshservice

• Access your DNS administration interface.
• A TXT record with the label selector._domainkey.yourdomainname.com should be created in your DNS system, for instance: s1._domainkey.yourdomainname.com
• Paste the copied DKIM public key contents in the section designated for the TXT record value (the DKIM public and private key pair will be provided by Freshservice on request)
• Click “Save.”

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