&amp;#039;&amp;#039;&amp;#039;Sender ID&amp;#039;&amp;#039;&amp;#039; is an E-Mail Authentication proposal that builds upon [[Sender Policy Framework (SPF)|SPF]]. It&amp;#039;s an attempt to validate not only the [[:Category:Authentication|RFC5321.MailFrom]], but also the [[:Category:Authentication|RFC5322.From domain]] and other headers.&lt;br /&gt;
&lt;br /&gt;
Sender ID was created by the [https://www.ietf.org/ IETF] [https://en.wikipedia.org/wiki/MARID MARID] working group and partly patented by [https://www.microsoft.com Microsoft]. Sender ID is defined in [https://www.rfc-editor.org/rfc/rfc4406 RFC 4406] with additional parts in [https://www.rfc-editor.org/rfc/rfc4405 RFC 4405], RFC [https://www.rfc-editor.org/rfc/rfc4407 RFC 4407] and RFC [https://www.rfc-editor.org/rfc/rfc4408 RFC 4408].&lt;br /&gt;
&lt;br /&gt;
Due to standardization and licensing issues, SenderID was deprecated before it even came out of the experimental stage.&lt;br /&gt;
