How to configure a Sender Policy Framework (SPF) record

This guide will show you how to configure your SPF record.

  1. Here is the configuration to use in your DNS server (without quotes):


yourdomain.com TXT "v=spf1 a mx ptr ip4:173.193.244.218 ip4:173.193.244.219 ip6:2607:f0d0:3005:008a:0000:0000:0000:0002 ip6:2607:f0d0:3005:008a:0000:0000:0000:0003 -all"

Note:

The Sender Policy Framework (SPF) is a technical method to prevent sender address forgery.
