Sender Policy Framework (SPF)
Sender Policy Framework (SPF), formerly Sender Permitted From, is an extension to the SMTP standard. SPF makes it easy to counter most forged "From" addresses in email, and thus helps to counter e-mail spam. The combination is also called SMTP+SPF.How does SPF work?
SPF is a mechanism where domain owner announce where email can come from for their domain. This announcement is done through a DNS server. For example, Microsoft exposes their SPF record in their DNS, which lists a set of IP addresses where an email can originate if the domain name is microsoft.com. If a message comes from any other IP address it should be considered as a forgery.How can I create an SPF record for my domain?
Xeams comes with an SPF wizard that allows you to create an SPF string. Once the string is create, you need to create a TXT record in your DSN with this string. Following steps show you how to use this wizard.- Log in to the Admin Console
- Click Tools on the main menu
