<p>To control which headers in the message should be displayed, <code>mail</code>
keeps two lists: a <em>retained</em> header list and an <em>ignored</em>
header list.  If <em>retained</em> header list is not empty, only the
header fields listed in it are displayed when printing the message.
Otherwise, if <em>ignored</em> header list is not empty, only the headers
<em>not listed</em> in this list are displayed.  The uppercase variants
of message-displaying commands can be used to print all the headers.
</p>
<p>The following commands modify and display the contents of both lists.
</p>
<dl compact="compact">
<dt>&lsquo;<samp>discard [<var>header-field-list</var>]</samp>&rsquo;</dt>
<dt>&lsquo;<samp>di [<var>header-field-list</var>]</samp>&rsquo;</dt>
<dt>&lsquo;<samp>ignore [<var>header-field-list</var>]</samp>&rsquo;</dt>
<dt>&lsquo;<samp>ig [<var>header-field-list</var>]</samp>&rsquo;</dt>
<dd><p>Add <var>header-field-list</var> to the ignored list.  When used without
arguments, this command prints the contents of ignored list.
</p></dd>
<dt>&lsquo;<samp>retain [<var>header-field-list</var>]</samp>&rsquo;</dt>
<dt>&lsquo;<samp>ret [<var>header-field-list</var>]</samp>&rsquo;</dt>
<dd><p>Add <var>header-field-list</var> to the retained list.  When used without
arguments, this command prints the contents of retained list.
</p></dd>
