What is a SPF (sender policy framework) Record?

The SPF record is used by many email systems to help identify the sender’s email is coming from a trusted source. This helps prevent SPAM and helps filter messages pretending to be from your domain (email spoofing).

A SPF record is entered into your DNS zone as a TXT Value like this:

Host Name TXT Value TTL (time to live)
@ v=spf1 a mx ptr include:rolethosting.com -all 1 Hour

SPF Records & 3rd Party Services

If you use 3rd party websites or 3rd party service providers to send email from your domain, you should add their domain to your SPF Record. Email may not be delivered if their system is not entered as a trusted source.

Please contact your 3rd party providers and ask them for the domain that they include in their SPF Record. You can then update the TXT Value with the new SPF Record. Here is a simple example:

Host Name TXT Value TTL (time to live)
@ v=spf1 a mx ptr include:rolethosting.com otherhost.com -all 1 Hour
