How to Set Up DKIM for Redtail?
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.
Steps to Configure DKIM Record for Redtail
To obtain your DKIM keys and enable DKIM authentication for your domains, contact Redtail support staff. You will receive a DKIM key pair from Redtail’s support that will include:
- A DKIM public key: to be made available in your public DNS.
- A DKIM private key, which you must upload to Redtail’s web server in order for them to sign your outgoing emails.
