Sender Policy Framework (SPF)

Sender Policy Framework (SPF) is an email authentication standard developed by AOL that compares the email sender’s actual IP address to a list of IP addresses authorized to send mail from that domain. The IP list is published in the domain’s DNS record

If you specify to use a custom domain name, in a template set, you must complete the following steps to ensure the e-mail is not being threated as spam.

SPF uses the domain value in the Return-Path header for the DNS lookup to determine the permitted senders for the domain.

If you have an SPF record set for your root domain (i.e. yourdomain.com), you must add the following:
