A SPF (Sender Policy Framework)  is a way to allow you to restrict which mail servers are allowed to send email for your domain name.

An example of an SPF would be : example.com. TXT "v=spf1 -all"

SPF records are TXT records placed into a domains DNS. To setup a SPF record we recommend using the following link:



Please note, forwarding emails can sometimes break the SPF. If this is the case we reccomend using SRS (Sender Rewriting Scheme). More information about this can be found here:


If the above links do not work please see http://www.open-spf.org/Tools/

***** Additional notes for Webservio customers:

If you are using Webservio Strata Mail email systems the SPF should be :

"v=spf1 a mx ip4: ip4: ip4:  -all"
