Sender ID
Sender ID , also known as Sender ID Framework (SIDF) , is an experimental method of the Internet Engineering Task Force (IETF) to combat spam in e-mail . It is based on the Sender Policy Framework and Microsoft's Caller ID .
The responsible IETF working group "marid" (" MTA Authorization Records in DNS ") stopped working on the specification of Sender ID on September 23, 2004 due to serious differences. The main reason for the failure is that Microsoft holds patents on key technologies from Sender ID and at the time made them available under a license that made it impossible for free software providers to implement them under the GNU General Public License or a similar open source license .
Microsoft planned to increase the use of Sender ID by classifying incoming e-mails without Sender ID as potential spam by the in-house services MSN and Hotmail . This procedure was justified with a large number of e-mails that would already have the characteristics of Sender ID. Experts criticized this approach and feared that Microsoft wanted to force the industry to use a standard that was not generally accepted. On October 24, 2006, Microsoft released the Sender ID procedure for all use as part of the Open Specification Promise project.
