+You may also have compiled Mutt to co-operate with Mixmaster, an
+anonymous remailer. Mixmaster permits you to send your messages
+anonymously using a chain of remailers. Mixmaster support in Mutt is for
+mixmaster version 2.04 or later.
+</p><p>
+To use it, you'll have to obey certain restrictions. Most important,
+you cannot use the <code class="literal">Cc</code> and <code class="literal">Bcc</code>
+headers. To tell Mutt to use mixmaster, you have to select a remailer
+chain, using the mix function on the compose menu.
+</p><p>
+The chain selection screen is divided into two parts. In the (larger)
+upper part, you get a list of remailers you may use. In the lower part,
+you see the currently selected chain of remailers.
+</p><p>
+You can navigate in the chain using the
+<code class="literal"><chain-prev></code> and
+<code class="literal"><chain-next></code> functions, which are by default
+bound to the left and right arrows and to the <code class="literal">h</code> and
+<code class="literal">l</code> keys (think vi keyboard bindings). To insert a
+remailer at the current chain position, use the
+<code class="literal"><insert></code> function. To append a remailer behind
+the current chain position, use <code class="literal"><select-entry></code>
+or <code class="literal"><append></code>. You can also delete entries from
+the chain, using the corresponding function. Finally, to abandon your
+changes, leave the menu, or <code class="literal"><accept></code> them
+pressing (by default) the <code class="literal">Return</code> key.
+</p><p>
+Note that different remailers do have different capabilities, indicated
+in the %c entry of the remailer menu lines (see <a class="link" href="reference.html#mix-entry-format" title="3.144. mix_entry_format">$mix_entry_format</a>). Most important is
+the <span class="quote">“<span class="quote">middleman</span>”</span> capability, indicated by a capital
+<span class="quote">“<span class="quote">M</span>”</span>: This means that the remailer in question cannot be
+used as the final element of a chain, but will only forward messages to
+other mixmaster remailers. For details on the other capabilities,
+please have a look at the mixmaster documentation.
