-<para>
-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 (beta 45 appears to be the latest) and 2.03.
-It does not support earlier versions or the later so-called version 3 betas,
-of which the latest appears to be called 2.9b23.
-</para>
-
-<para>
-To use it, you'll have to obey certain restrictions. Most
-important, you cannot use the <literal>Cc</literal> and <literal>Bcc</literal> headers. To tell
-Mutt to use mixmaster, you have to select a remailer chain, using
-the mix function on the compose menu.
-</para>
-
-<para>
-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.
-</para>
-
-<para>
-You can navigate in the chain using the <literal><chain-prev></literal> and
-<literal><chain-next></literal> functions, which are by default bound to the left
-and right arrows and to the <literal>h</literal> and <literal>l</literal> keys (think vi
-keyboard bindings). To insert a remailer at the current chain
-position, use the <literal><insert></literal> function. To append a remailer behind
-the current chain position, use <literal><select-entry></literal> or <literal><append></literal>.
-You can also delete entries from the chain, using the corresponding
-function. Finally, to abandon your changes, leave the menu, or
-<literal><accept></literal> them pressing (by default) the <literal>Return</literal> key.
-</para>
-
-<para>
-Note that different remailers do have different capabilities,
-indicated in the %c entry of the remailer menu lines (see
-<link linkend="mix-entry-format">$mix_entry_format</link>). Most important is
-the <quote>middleman</quote> capability, indicated by a capital <quote>M</quote>: 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.
