How does email SPF work?
Servers receiving messages verify SPF by querying the domain’s Return-Path value found in the headers of the email. The recipient server uses this Return-Path to check for a TXT record in the sender’s DNS server. If SPF is in place, it will list all approved servers mail is allowed to come from.
Does SPF prevent spam?
