How to create an SPF record

Create an SPF record

  1. Log in to the control panel for your domain DNS host.

  2. Create a TXT record with the following specifications. 

    v=spf1 include:emailsrvr.com ~all

    In addition to validating the original source of the message, these signatures ensure that the message has not been altered in transit by any third parties.

  3. Decide how you want to enforce SPF failures.

    • ~all will result in a soft fail (Not authorized, but not explicitly unauthorized).
    • -all will result in a hard fail (Unauthorized).
    • ?all is neutral (As if there is no policy at all).

    Enter your choice after v=spf1 include:emailsrvr.com, and then save your changes.

  4. Authorize additional mail servers by adding their IP or server name after include:.

    • For example:
    Type Hostname Destination TTL
    TXT @ v=spf1 include:emailsrvr.com include:othermailer.com ~all 3600
  5. Save your changes.
