The Sender ID Framework is a new authentication protocol that can be used to counter spoofing by people who send unsolicited commercial e-mail messages (spam). Spoofing is the practice of forging a sender's address on e-mail messages. Spoofing misleads e-mail recipients and makes them read and respond to deceptive e-mail messages. To safeguard Internet domain names, and to help e-mail recipients identify junk e-mail messages and phishing scams more effectively, administrators can publish SPF records in the public DNS.
- Click Start, point to All Programs, point to Administrative Tools, and then click DNS.
- In the left pane, expand the DNS server object, and then expand Forward Lookup Zones.
- Right-click the domain folder to which you want to add the SPF record, and then click Other New Records.
- In the Select a resource record type list, click Text (TXT), and then click Create Record.
- If you add a record for the parent domain, leave the Record name box blank. If you do not add a record for the parent domain, type the single part name of the domain in the Record name box.
- In the Text box, type v=spf1 mx -all.
- Click OK, and then click Done.
