'''Mixmaster''' is a Type II [[anonymous remailer]] which sends messages in fixed-size packets and reorders them, preventing anyone watching the messages go in and out of remailers from tracing them.  It is an implementation of a [[David Chaum]]'s [[mix network]].<ref>

== History ==
Mixmaster was originally written by Lance Cottrell, and was maintained by [[Len Sassaman]]. [[Peter Palfrader]] is the current maintainer. Current Mixmaster software can be compiled to handle [[Cypherpunk anonymous remailer|Cypherpunk]] messages as well; they are needed as reply blocks for [[nym server]]s.

Support for Mixmaster was removed from the Neomutt fork of the [[Mutt (email client)|Mutt mail client]] in 2024 because the project did not seem active anymore.<ref>{{cite web | url=https://github.com/neomutt/neomutt/commit/b0e085e142dfc60eeaf661373f3930aa3cc4b83d | title=Remove mixmaster · neomutt/Neomutt@b0e085e | website=[[GitHub]] }}</ref>
