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 (Do not click any item in the pop-up menu - click Tools itself)
  • Scroll down and type your domain name for SPF Wizard and click Proceed
  • The generated string must be added in your DNS server as a TXT record

Hi, this post is not so clear, especially after the below points; "Scroll down and type your domain name for SPF Wizard and click Proceed" "The generated string must be added in your DNS server as a TXT record" Are you able to be more precise?

Truth be told, DKIM and DMARC are really necessary feature nowadays. This is something that would really help to filter spam messages a lot.

For SPF Record, I type my domain name and click Proceed. The next page says "NS Record" and shows some values. How do I add, change, or delete values for NS record?

What about DKIM? Can Xeams validate DKIM? I am just learning about DKIM and am looking to put it in place. However I am not 100% how it is truely useful in validation.

YES DKIM added http://www.xeams.com/DKIM.htm Thanks, please also add DMARC And even better add fields/items on message that make it possible in WEBMAIL or Email Clients to see this message has this status/remark for Antivirus SPF DKIM DMARC Example: DMARC - No DKIM, but maybe legit, as SPF are okay.
