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. 

If Pobox manages your DNS, there is no need to do anything because DKIM is already configured. If not, you will need to publish the DKIM key using your DNS, which Pobox will supply. By visiting the MyPobox Page in the Pobox, you can get access to the DKIM public key for your domain. Don’t forget to copy the DKIM key to your clipboard. Once this is done proceed to publish your DKIM Key for Pobox.

How to publish the DKIM Keys in DNS for Pobox:

  • 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 DKIM public key’s copied contents into the space designated for the TXT record value.
  • Click “Save.”
