<P>

<dl><dt><b><a name='l2h-2076'><tt class='method'>getwelcome</tt></a></b> ()
<dd>
Returns the greeting string sent by the POP3 server.
</dl>

<P>
<dl><dt><b><a name='l2h-2077'><tt class='method'>user</tt></a></b> (<var>username</var>)
<dd>
Send user command, response should indicate that a password is required.
</dl>

<P>
<dl><dt><b><a name='l2h-2078'><tt class='method'>pass_</tt></a></b> (<var>password</var>)
<dd>

Note: the mailbox on the server is locked until <tt class="method">quit()</tt> is
called.
</dl>

<P>
<dl><dt><b><a name='l2h-2079'><tt class='method'>apop</tt></a></b> (<var>user, secret</var>)
<dd>
Use the more secure APOP authentication to log into the POP3 server.

<P>
<dl><dt><b><a name='l2h-2080'><tt class='method'>rpop</tt></a></b> (<var>user</var>)
<dd>

</dl>

<P>
<dl><dt><b><a name='l2h-2082'><tt class='method'>list</tt></a></b> (<big>[</big><var>which</var><big>]</big>)
<dd>

<code>(<var>response</var>, ['mesg_num octets', ...])</code>.  If <var>which</var> is
set, it is the message to list.
</dl>

<P>
<dl><dt><b><a name='l2h-2083'><tt class='method'>retr</tt></a></b> (<var>which</var>)
<dd>
Retrieve whole message number <var>which</var>.  Result is in form 
<code>(<var>response</var>, ['line', ...], <var>octets</var>)</code>.
</dl>

<P>
<dl><dt><b><a name='l2h-2084'><tt class='method'>dele</tt></a></b> (<var>which</var>)
<dd>

<P>
<dl><dt><b><a name='l2h-2085'><tt class='method'>rset</tt></a></b> ()
<dd>

</dl>

<P>
<dl><dt><b><a name='l2h-2086'><tt class='method'>noop</tt></a></b> ()
<dd>
Do nothing.  Might be used as a keep-alive.
</dl>

<P>
<dl><dt><b><a name='l2h-2087'><tt class='method'>quit</tt></a></b> ()
<dd>
Signoff:  commit changes, unlock mailbox, drop connection.
</dl>

<P>
<dl><dt><b><a name='l2h-2088'><tt class='method'>top</tt></a></b> (<var>which, howmuch</var>)
<dd>
Retrieves the message header plus <var>howmuch</var> lines of the message
after the header of message number <var>which</var>. Result is in form 
<code>(<var>response</var>, ['line', ...], <var>octets</var>)</code>.
</dl>

<P>
<dl><dt><b><a name='l2h-2089'><tt class='method'>uidl</tt></a></b> (<big>[</big><var>which</var><big>]</big>)
<dd>
Return message digest (unique id) list.
If <var>which</var> is specified, result contains the unique id for that
message in the form <code>'<var>response</var> <var>mesgnum</var> <var>uid</var></code>,
otherwise result is list <code>(<var>response</var>, ['mesgnum uid', ...],
<var>octets</var>)</code>.
