What is an SPF (Send Policy Framework) record?

By adding one or several SPF-records (Send Policy Framework) to the nameserver, you can determine which mailservers are allowed to send e-mails. This way, the receiving mailserver can check if the e-mail is sent from one of the allowed mailservers. If not, the mail can be refused. Not all receiving mailservers support SPF, but it is upcoming.


You can find a wizard on http://www.microsoft.com/mscorp/safety/content/technologies/senderid/wizard/ to determine the right configuration. You can add the SPF-record in your Domain Manager: 'Nameservers –Subdomains’, click on ‘Configure Nameserver’, click on ‘Edit’. Under section 'Other configuration' you can add your SPF-record.
