What is SPF validation?
Sender Policy Framework (SPF) is an email authentication method designed to detect forging sender addresses during the delivery of the email. The list of authorized sending hosts and IP addresses for a domain is published in the DNS records for that domain.
What does SPF fail mean?
~ SoftFail, an IP that matches a mechanism with this qualifier will soft fail SPF, which means that the host should accept the mail, but mark it as an SPF failure.
How can I tell if SPF is working?
You can manually check the Sender Policy Framework (SPF) record for a domain by using nslookup as follows:
- Open Command prompt (Start > Run > cmd)

- If an SPF record exists, the result would be similar to:
Does SPF prevent spoofing?

What do SPF records do?
