How to Set Up DKIM for Suresupport?

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. 

Steps to Configure DKIM for Suresupport

You must click the Enable button in the Mailprotection section of the DNS manager in the Control panel if your domain is hosted by suresupport. The mail server produces the private key and public key when you enable DKIM protection.

  1. A DKIM public key, which should be published in your public DNS.
  2. A DKIM private key: used by Suresupport to sign your outgoing emails

You must replicate the DNS records on any external DNS servers you use. However, if suresupport is hosting your domain, their DNS servers will be instantly changed.

If you are sending emails from your own servers rather than suresupport’s, you can produce your DKIM key pair using our free DKIM record generating tool.

How to Get Your DKIM Public Key Available for Suresupport

  1. Sign in as the administrator to your DNS provider’s administration console.
  2. Go to the DNS records section of each of your domains.
  3. Depending on the type of DKIM record that has been provided to you, generate a TXT or CNAME record.
  4. Copy and paste the hostname and value
  5. Save your record’s modifications and wait 48–72 hours for your DNS to take effect.
