−summary: Workaround for Dialback with some servers that violate RFC 6120
+
−...
+
−
+
−This module provides a workaround for servers that do not set the `to`
+
−attribute on stream headers, which is required per [RFC6120]:
+
−
+
−> ## 4.7.2. to
+
−> 
+
−> For initial stream headers in both client-to-server and
+
−> server-to-server communication, the initiating entity MUST include the
+
−> 'to' attribute and MUST set its value to a domainpart that the
+
−> initiating entity knows or expects the receiving entity to service.
+
−
+
−As a side effect of [this issue](https://prosody.im/issues/issue/285),
+
−Prosody 0.10 will be unable to do [Dialback][xep220] with servers that
+
−don't follow this.
