<h2>Detailed Description</h2>
<p>The QMailMessagePart class provides a convenient interface for working with message attachments.</p>
<p>A message part inherits the properties of <a href="qmailmessagepartcontainer.html">QMailMessagePartContainer</a>, and can therefore contain a message body or a collection of sub-parts.</p>
<p>A message part differs from a message proper in that a part will often have properties specified by the MIME multipart specification, not relevant to messages. These include the 'name' and 'filename' parameters of the Content-Type and Content-Disposition fields, and the Content-Id and Content-Location fields.</p>
<p>A message part may consist entirely of a reference to an external message, or a part within an external message. Parts that consists of references may be used with some protocols that permit data to be transmitted by reference, such as IMAP with the URLAUTH extension. Not all messaging protocols support the use of content references. The <a href="qmailmessagepart.html#partReference">partReference</a>() and <a href="qmailmessagepart.html#messageReference">messageReference</a>() functions enable the creation of reference parts.</p>
