<p>This module defines three classes, <a class="reference internal" href="#imaplib.IMAP4" title="imaplib.IMAP4"><tt class="xref py py-class docutils literal"><span class="pre">IMAP4</span></tt></a>, <a class="reference internal" href="#imaplib.IMAP4_SSL" title="imaplib.IMAP4_SSL"><tt class="xref py py-class docutils literal"><span class="pre">IMAP4_SSL</span></tt></a> and
<a class="reference internal" href="#imaplib.IMAP4_stream" title="imaplib.IMAP4_stream"><tt class="xref py py-class docutils literal"><span class="pre">IMAP4_stream</span></tt></a>, which encapsulate a connection to an IMAP4 server and
implement a large subset of the IMAP4rev1 client protocol as defined in
<span class="target" id="index-1"></span><a class="rfc reference external" href="http://tools.ietf.org/html/rfc2060.html"><strong>RFC 2060</strong></a>. It is backward compatible with IMAP4 (<span class="target" id="index-2"></span><a class="rfc reference external" href="http://tools.ietf.org/html/rfc1730.html"><strong>RFC 1730</strong></a>) servers, but
note that the <tt class="docutils literal"><span class="pre">STATUS</span></tt> command is not supported in IMAP4.</p>
<p>Three classes are provided by the <a class="reference internal" href="#module-imaplib" title="imaplib: IMAP4 protocol client (requires sockets)."><tt class="xref py py-mod docutils literal"><span class="pre">imaplib</span></tt></a> module, <a class="reference internal" href="#imaplib.IMAP4" title="imaplib.IMAP4"><tt class="xref py py-class docutils literal"><span class="pre">IMAP4</span></tt></a> is the
base class:</p>
<dl class="class">

<dd><p>This class implements the actual IMAP4 protocol.  The connection is created and
protocol version (IMAP4 or IMAP4rev1) is determined when the instance is
initialized. If <em>host</em> is not specified, <tt class="docutils literal"><span class="pre">''</span></tt> (the local host) is used. If
<em>port</em> is omitted, the standard IMAP4 port (143) is used.</p>
</dd></dl>

<p>Three exceptions are defined as attributes of the <a class="reference internal" href="#imaplib.IMAP4" title="imaplib.IMAP4"><tt class="xref py py-class docutils literal"><span class="pre">IMAP4</span></tt></a> class:</p>
<dl class="exception">

<dd><p>IMAP4 server errors cause this exception to be raised.  This is a sub-class of
<a class="reference internal" href="#imaplib.IMAP4.error" title="imaplib.IMAP4.error"><tt class="xref py py-exc docutils literal"><span class="pre">IMAP4.error</span></tt></a>.  Note that closing the instance and instantiating a new one
will usually allow recovery from this exception.</p>
</dd></dl>

<dl class="exception">
<dt id="imaplib.IMAP4.readonly">
<em class="property">exception </em><tt class="descclassname">IMAP4.</tt><tt class="descname">readonly</tt><a class="headerlink" href="#imaplib.IMAP4.readonly" title="Permalink to this definition">¶</a></dt>
<dd><p>This exception is raised when a writable mailbox has its status changed by the
server.  This is a sub-class of <a class="reference internal" href="#imaplib.IMAP4.error" title="imaplib.IMAP4.error"><tt class="xref py py-exc docutils literal"><span class="pre">IMAP4.error</span></tt></a>.  Some other client now has
write permission, and the mailbox will need to be re-opened to re-obtain write
permission.</p>
</dd></dl>

<p>There&#8217;s also a subclass for secure connections:</p>
<dl class="class">
<dt id="imaplib.IMAP4_SSL">
<em class="property">class </em><tt class="descclassname">imaplib.</tt><tt class="descname">IMAP4_SSL</tt><big>(</big><span class="optional">[</span><em>host</em><span class="optional">[</span>, <em>port</em><span class="optional">[</span>, <em>keyfile</em><span class="optional">[</span>, <em>certfile</em><span class="optional">]</span><span class="optional">]</span><span class="optional">]</span><span class="optional">]</span><big>)</big><a class="headerlink" href="#imaplib.IMAP4_SSL" title="Permalink to this definition">¶</a></dt>
<dd><p>This is a subclass derived from <a class="reference internal" href="#imaplib.IMAP4" title="imaplib.IMAP4"><tt class="xref py py-class docutils literal"><span class="pre">IMAP4</span></tt></a> that connects over an SSL
encrypted socket (to use this class you need a socket module that was compiled
with SSL support).  If <em>host</em> is not specified, <tt class="docutils literal"><span class="pre">''</span></tt> (the local host) is used.
If <em>port</em> is omitted, the standard IMAP4-over-SSL port (993) is used.  <em>keyfile</em>
and <em>certfile</em> are also optional - they can contain a PEM formatted private key
and certificate chain file for the SSL connection.</p>
</dd></dl>

<p>The second subclass allows for connections created by a child process:</p>
<dl class="class">
<dt id="imaplib.IMAP4_stream">
<em class="property">class </em><tt class="descclassname">imaplib.</tt><tt class="descname">IMAP4_stream</tt><big>(</big><em>command</em><big>)</big><a class="headerlink" href="#imaplib.IMAP4_stream" title="Permalink to this definition">¶</a></dt>

<tt class="docutils literal"><span class="pre">stdin/stdout</span></tt> file descriptors created by passing <em>command</em> to
<tt class="docutils literal"><span class="pre">os.popen2()</span></tt>.</p>
<p class="versionadded">
<span class="versionmodified">New in version 2.3.</span></p>
</dd></dl>

<p>The following utility functions are defined:</p>
<dl class="function">
<dt id="imaplib.Internaldate2tuple">
<tt class="descclassname">imaplib.</tt><tt class="descname">Internaldate2tuple</tt><big>(</big><em>datestr</em><big>)</big><a class="headerlink" href="#imaplib.Internaldate2tuple" title="Permalink to this definition">¶</a></dt>

</dd></dl>

<dl class="function">

<dd><p>Convert <em>date_time</em> to an IMAP4 <tt class="docutils literal"><span class="pre">INTERNALDATE</span></tt> representation.  The
return value is a string in the form: <tt class="docutils literal"><span class="pre">&quot;DD-Mmm-YYYY</span> <span class="pre">HH:MM:SS</span>
<span class="pre">+HHMM&quot;</span></tt> (including double-quotes).  The <em>date_time</em> argument can be a
number (int or float) representing seconds since epoch (as returned
by <a class="reference internal" href="time.html#time.time" title="time.time"><tt class="xref py py-func docutils literal"><span class="pre">time.time()</span></tt></a>), a 9-tuple representing local time (as returned by
<a class="reference internal" href="time.html#time.localtime" title="time.localtime"><tt class="xref py py-func docutils literal"><span class="pre">time.localtime()</span></tt></a>), or a double-quoted string.  In the last case, it
is assumed to already be in the correct format.</p>
</dd></dl>

<p>Note that IMAP4 message numbers change as the mailbox changes; in particular,
after an <tt class="docutils literal"><span class="pre">EXPUNGE</span></tt> command performs deletions the remaining messages are
renumbered. So it is highly advisable to use UIDs instead, with the UID command.</p>
<p>At the end of the module, there is a test section that contains a more extensive
example of usage.</p>

<span id="id1"></span><h2>20.10.1. IMAP4 Objects<a class="headerlink" href="#imap4-objects" title="Permalink to this headline">¶</a></h2>
<p>All IMAP4rev1 commands are represented by methods of the same name, either
upper-case or lower-case.</p>
<p>All arguments to commands are converted to strings, except for <tt class="docutils literal"><span class="pre">AUTHENTICATE</span></tt>,
and the last argument to <tt class="docutils literal"><span class="pre">APPEND</span></tt> which is passed as an IMAP4 literal.  If
necessary (the string contains IMAP4 protocol-sensitive characters and isn&#8217;t
enclosed with either parentheses or double quotes) each string is quoted.
However, the <em>password</em> argument to the <tt class="docutils literal"><span class="pre">LOGIN</span></tt> command is always quoted. If
you want to avoid having an argument string quoted (eg: the <em>flags</em> argument to
<tt class="docutils literal"><span class="pre">STORE</span></tt>) then enclose the string in parentheses (eg: <tt class="docutils literal"><span class="pre">r'(\Deleted)'</span></tt>).</p>
<p>Each command returns a tuple: <tt class="docutils literal"><span class="pre">(type,</span> <span class="pre">[data,</span> <span class="pre">...])</span></tt> where <em>type</em> is usually
<tt class="docutils literal"><span class="pre">'OK'</span></tt> or <tt class="docutils literal"><span class="pre">'NO'</span></tt>, and <em>data</em> is either the text from the command response,
or mandated results from the command. Each <em>data</em> is either a string, or a
tuple. If a tuple, then the first part is the header of the response, and the
second part contains the data (ie: &#8216;literal&#8217; value).</p>
<p>The <em>message_set</em> options to commands below is a string specifying one or more
messages to be acted upon.  It may be a simple message number (<tt class="docutils literal"><span class="pre">'1'</span></tt>), a range
of message numbers (<tt class="docutils literal"><span class="pre">'2:4'</span></tt>), or a group of non-contiguous ranges separated by
commas (<tt class="docutils literal"><span class="pre">'1:3,6:9'</span></tt>).  A range can contain an asterisk to indicate an infinite
upper bound (<tt class="docutils literal"><span class="pre">'3:*'</span></tt>).</p>
<p>An <a class="reference internal" href="#imaplib.IMAP4" title="imaplib.IMAP4"><tt class="xref py py-class docutils literal"><span class="pre">IMAP4</span></tt></a> instance has the following methods:</p>
