Headers are <span class="target" id="index-0"></span><a class="rfc reference external" href="https://tools.ietf.org/html/rfc5322.html"><strong>RFC 5322</strong></a> or <span class="target" id="index-1"></span><a class="rfc reference external" href="https://tools.ietf.org/html/rfc6532.html"><strong>RFC 6532</strong></a> style field names and values, where the field name and value are separated by a colon. The colon is not part of either the field name or the field value. The payload may be a simple text message, or a binary object, or a structured sequence of sub-messages each with their own set of headers and their own payload. The latter type of payload is indicated by the message having a MIME type such as <em class="mimetype">multipart/*</em> or <em class="mimetype">message/rfc822</em>.</p> <p>The conceptual model provided by an <a class="reference internal" href="#email.message.EmailMessage" title="email.message.EmailMessage"><code class="xref py py-class docutils literal notranslate"><span class="pre">EmailMessage</span></code></a> object is that of an ordered dictionary of headers coupled with a <em>payload</em> that represents the <span class="target" id="index-2"></span><a class="rfc reference external" href="https://tools.ietf.org/html/rfc5322.html"><strong>RFC 5322</strong></a> body of the message, which might be a list of sub-<code class="docutils literal notranslate"><span class="pre">EmailMessage</span></code> objects. In addition to the normal dictionary methods for accessing the header names and values, there are methods for accessing specialized information from the headers (for example the MIME content type), for operating on the payload, for generating a serialized version of the message, and for recursively walking over the object tree.</p> <p>The <a class="reference internal" href="#email.message.EmailMessage" title="email.message.EmailMessage"><code class="xref py py-class docutils literal notranslate"><span class="pre">EmailMessage</span></code></a> dictionary-like interface is indexed by the header names, which must be ASCII values. The values of the dictionary are strings with some extra methods. Headers are stored and returned in case-preserving form, but field names are matched case-insensitively. Unlike a real dict, there is an ordering to the keys, and there can be duplicate keys. Additional methods are provided for working with headers that have duplicate keys.</p> <p>The <em>payload</em> is either a string or bytes object, in the case of simple message objects, or a list of <a class="reference internal" href="#email.message.EmailMessage" title="email.message.EmailMessage"><code class="xref py py-class docutils literal notranslate"><span class="pre">EmailMessage</span></code></a> objects, for MIME container documents such as <em class="mimetype">multipart/*</em> and <em class="mimetype">message/rfc822</em> message objects.</p> <dl class="class"> <dt id="email.message.EmailMessage"> <em class="property">class </em><code class="descclassname">email.message.</code><code class="descname">EmailMessage</code><span class="sig-paren">(</span><em>policy=default</em><span class="sig-paren">)</span><a class="headerlink" href="#email.message.EmailMessage" title="Permalink to this definition">¶</a></dt> <dd><p>If <em>policy</em> is specified use the rules it specifies to update and serialize the representation of the message.
