Sender ID Framework SPF Record Wizard

http://www.microsoft.com/mscorp/safety/content/technologies/senderid/wizard/

This four-step wizard will guide you through the process of creating a new SPF record for your DNS domain.  You should add this DNS record to your domain's DNS configuration.   Note that you may need to manually edit the SPF record created by this wizard if you want to use some of the more advance features of the SPF format.  For complete details please refer to the SPF record specification at http://www.microsoft.com/senderid.

How does Sender ID Framework work?

1. Sender sends an e-mail to Receiver.
2. Receiver’s inbound e-mail server receives e-mail and calls its Sender ID Framework.
3. The Sender ID Framework looks up the SPF record of the domain that Sender is using for sending the mail.
4. The receiving Mail Transfer Agent (MTA) determines if the outbound Mail Server IP address matches IP addresses that are authorized to send mail for the user.
