<li>Enable a sender to request notification that an XMPP message stanza has been received.</li>
<li>Enable a recipient to provide message receipts if desired.</li>
</ol>
<p>Note: This document explicitly does not define a protocol for "guaranteed delivery", since that term (like "security") means different things to different people. Instead, we define a more focused protocol that addresses the need for message receipts, thus solving one problem that falls under the heading of "guaranteed delivery".</p>
</section1>
<section1 topic='Reliability' anchor='reliability'>
<p>This document defines a protocol that enables a sender to ask the recipient to return a receipt for a message. Although the return of a message receipt lets the sender know that the message has been delivered, there are many reasons why the sender might not receive a receipt immediately or at all, including but not limited to the following:</p>
<ul>
<li>The recipient (or the particular intended resource to which the sender addressed the message) does not in fact support message receipts.</li>
<li>The intended resource supports message receipts but the recipient's server delivers the message to another resource that does not support message receipts.</li>
<li>The recipient's client receives the message but experiences a malfunction before generating a receipt.</li>
<li>The recipient returns a receipt but the receipt is lost on the way back from the recipient to the sender (e.g., because of connectivity issues or software failures at any hop).</li>
</ul>
<p>Therefore this document does not define a protocol for complete reliability or guaranteed delivery, and those who implement and deploy this protocol need to be aware of its limitations.</p>
</section1>
<section1 topic='Protocol Format' anchor='format'>
<p>In order to make it possible for senders to request and for recipients to generate message receipts, we define a dedicated protocol extension qualified by the 'urn:xmpp:receipts' namespace.</p>
