What is SPF?

  • Sender Policy Framework (SPF) is a simple email-validation system to detect mail spoofing from forged "From" addresses.  
     
  • The framework verifies that the sending host is authorized to send mails from the domain in the 'From' field of the mail.
     
  • You add SPF records to your domain name system (DNS) to notify your recipients of the hosts which are allowed to send emails from your domain.
     
  • An SPF record contains the IP addresses of authorized hosts in the form of a specially formatted TXT record.
     
  • Adding an SPF record to your DNS can overcome situations where a recipient mail server rejects mails from Service Desk to your end-users.
     
  • This article explains how to add SPF records if you are using Outlook email setup for your domain.

Add an SPF record

  • Go to the DNS management page of your domain.
     
  • Add a new DNS record with the values as follows:
     
    • Type = “TXT”
       
    • Hostname / Host / Name = Your domain name. Type "@" to map the record directly to your domain name, or enter the subdomain of your host name (labeled host), such as www or ftp.
       
    • TXT value =  'v=spf1 ip4:34.251.73.164 ip4:23.236.135.67 include:spf.protection.outlook.com -all'
       
    • TTL: Select how long the server should cache the information
       
  • Save the record.
     
  • See the reference manual of your hosting / DNS service provider if you need help with creating a new DNS record for your domain.
