 Example:

Let's say that you are planning to send emails using Google Apps and you also want to ensure that no other mail servers are authorised. You can use an SPF record like this:


v=spf1 include:_spf.google.com -all


"v=spf1" - This sets the SPF version 
"include:_spf.google.com" - This includes Google mail servers in your list of authorized sending servers 
"-all" - This means that any server not previously listed is not authorized 

If you are using your own VPS to send email and not any other service like Mandrill, Google Apps, etc. then you can create an SPF record like this:


v=spf1 mx -all
