Mixminion Message Sender
A Win32 Type III Anonymous Email Utility
Windows GUI Frontend for Mixminion
Mixminion is a third generation remailer design that is intended to make it possible to send anonymous email messages in such a manner that they cannot be traced back to their origin. Those interested in Mixminion's design details the Design document (PDF) should make for interesting reading.
Intended to make life easier for those using Mixminion in a Win32 enviroment because Mixminion itself is a command line program which is useful but I've found that it quickly gets cumbersome to use. Mixminion message Sender is a GUI frontend that handles some of the 'grunt work' involved in sending anonymous email messages and some of the functions that deal with Single Use Reply Blocks and the message queue.
There are now Three distributions, the original that does not include mixminion. One that that includes Mixminion 0.0.7.1 (the most recent "oficial" win32 version) ready to run. In an upcoming future update I will be adding a third distribution that includes an unofficial win32 build of Mixminion 0.0.8alpha3, which is the latest version.
The original distribution is here: MMS_1_2_7_dist.zip
The Archive contains three files:
The program distribution archive: MMS_1_2_7_dist.zip
and two detached pgp signatures. One, MMS_1_2_7..zip.dss.sig
created by DH/DSS key-id: 0xB9E76C70
(fingerprint: 4195 2FD1 5944 F13B 85B4 118B B718 E95C B9E7 6C70)
and for compatibility with pgp2.6.x users, another signature, MMS_1_2_7.zip.sig
created by RSA key-id: 0x72A69CD5
(fingerprint: 9751 781B E690 9145 9641 220D E9C1 5265)
The 'Mixminion 0.0.7.1 Included' distribution is here: MMS_1_2_7_dist_M.zip
The Archive contains three files:
The program distribution archive: MMS_1_2_7_dist_M.zip

You will need the Windows version of the Mixminion 0.0.7.1 Executable
The current version as of August 2005 is 0.0.7.1
Here's the url for downloading the win32 executeable for users without Python 2.3
and here's the detached pgp signature to verify it with
For those who have Python 2.3 installed, you can use this one:
and it's detached pgp signature
The mixminion source code is also available so that you can examine it and compile your own executeables. See http://mixminion.net for details.
Nothing fancy here, just a very basic windows mixminion tool.
Development news: In the spring of '06, while using Debian Linux because I was not able to use windows because of hardware foulups, I began new step in MMS development. MMS 2 is intended to be a cross-platform version that will run on linux as well as Windows. It is just begun and needs a bunch of work to get to the point where it has all of the functions of the win32 version but it does work.
Freenet users can also get these files anonymously with FUQID using these keys

Changelog 02/11/09 -1.2.7 I messed up and introduced a bug in the create dummy routine. Found and squashed. Found and fixed another bug in create surbs routine Added "use at your own risk" warning to the "'Mixminion 0.0.8alpha3 Included' distribution "section of the download page Updated readme.txt file 02/10/09 -1.2.6 Removed Beta designation. Over 3 years is more than long enough for "beta" (yikes! has it been THAT long?!) Added LineWrap code contributed by drsnoid. Messages are now word wrapped at 65 characters / line. Added "Word wrap on send" checkbox. Checked by default Created a third distribution using a copy of Mixminion 0.0.8alpha3 built and contributed by "Antonio from Italy" for those who want to use a win32 version of the most recent Mixminion release. I have been using this build since 5/23/2008 without any problems. Changed max newsgroups to 3 to prevent msgs from being lost in m2n's that only allow 3 since more and more are making this change in efforts to reduce excessive cross posting by trolls. Changed processing of the references line to make certain that message id's are separated by only one space character by removing all space and tab characters and replacing them with single space characters. Added Richtx32.ocx v6.0 to program directory so that MMS will work on Vista Note: this is un-tested on vista because the one vista machine I had access to refuses to boot anymore. Changed Mixminion command line to force mixminionrc to stay in the Mixminion program directory instead of it's default. This change makes MMS portable. I have tested it on Windows XP running it from a flash drive. I'll appreciate any reports from people who can try it out on vista. No testing done on Win 98, also because I don't have a win 98 machine available, however it should work fine. 05/18/08 -1.2.5-Beta Bugfix: error in mail2news gateway selection code caused @m2n.4096.net to be ignored. Code is fixed, but the gateway isn't working as of this release. Removed @newsanon.org from mail2news gateway list since it's been confirmed down for quite a while. Created a second distribution that includes mixminion already set up so that it's ready to run "out of the box" Changed dummy packet generation to allow creating multiple packets, default set to 3 packets at a time. Changed "Clear form" command so that it sets the mail2news gateway to @m2n.mixmin.net instead of "None" Set default update interval to 2 hours if "Auto Update Servers" is enabled. Changed minimum possible hops from 2 to 3 to insure minimum safe anonymous path Changed maximum possible hops to 29 after experiments showed it to work Changed SURB generation so that first and last hop select boxes and Number of hops droplist control the SURB path Made the 'get path' routine into a subroutine that's now called from several places instead of duplicating code 04/09/07 -1.2.4-Beta I created a bug with my last fix for the references line from a msg being replied to. I forgot to change a var name I was using for the attribution of quoted text which had it quoting the references line instead of the Message Id in the first line of a reply 04/02/07 -1.2.3-Beta Bugfix: A missed step was causing new newsgroup messages to error out because the command line had two '-t' arguments Changed reply parsing to include the entire 'references' line in the previous msg headers to improve threading. 11/28/06 -1.2.2-Beta Due to shutdown of Bigapple remailer and m2n, code specific to it has been removed. Added @m2n.4096.net to list of m2n choices. @anon.lcs.mit.edu and @newsanon.org are still in the m2n choice list, but their use is not recommended. lcs is often either down or just plain non-responsive and newsanon.org is operated by the eelbash remailer, which few if any knowledgable remailer users will recommend using. Users are advised to read alt.privacy.anon-server, ask questions search google and decide for themselves if they want to use it. 08/13/06 -1.2.1-Beta Added email@example.com and firstname.lastname@example.org to the mail2news gateway droplist. Changed message body text box to a Richtext box with right click menu enabled with basic cut-copy-paste-del-undo functions. Added 'Message Font Size' to 'Options' menu. Allows user to set the Font-Size used in the message body. Choices are 8,9,10,11,12,14 and 16 10/31/05 -1.2.0-Beta Added 'Auto Update Servers' to Options menu. If checked, the 'Update Servers' routine will execute automaticaly on a user settable timer from 20 to 720 minutes (20 min to 12 hours) Added 'Update Servers at Startup' to Options menu. If checked, 'Update Servers' will run at program start. Added 'Edit Mixminionrc' to the 'Mixminion' Menu. It will open the default mixminionrc file for editing in windows Notepad.exe. This assumes that mixminionrc is located in a subdirectory of the mixminion dir named ~ (that's a single tilde) ***USE CAUTION when editing this file*** the only entry most users will need to edit is the SURBLifetime: entry. 10/27/05 -1.1.9-Beta Using 'Reply to Clipboard' function when the windows clipboard did not contain a message was causing an 'input past end of file' error. Fixed by adding a check to make sure there is enough data in the clipboard to actually be a message. 09/24/05 -1.1.8-Beta Removed '--config=' options from all commandlines allowing the 'mixminionrc' config file to exist in it's default directory, which in windows is a subdirectory of the mixminion install dir named ~ (thats a single tilde) Changed Create SURB so that number of hops are now controlled by the setting on the main form Fixed Create surb not exiting subroutine when 'Cancel' button selected on any of it's inputs. Added msgbox in the create SURB routine to remind user about SURB lifetime and advise how to change the default seven day value. Added 'No SURB Lifetime Reminder' to Options menu, if checked, the above msgbox will stay quiet. The "Add" buttons no longer clear the value being added The 'Create Dummy Packet' function now uses the first and last hop selectors and the number of hops selector to determine dummy traffic paths. 08/04/05 -1.1.7-Beta Readme.txt file re-written. Added check of the mixminion path in line one of mms.ini. If it's not correct, ask the user for the correct value. Similar check added to the config form. 'Update Servers' function was using a hard-coded path to mixminionrc which caused a fatal error in mixminion if it was not installed in c:\mixminion. this *should* be the last thing in the way to installing in any path desired. Changed addressing error check, now if user has both 'To:' and 'Newsgroups:' message box asks to choose removing 'To:', remove 'Newsgroups:' or Cancel. Added option to automaticaly change mail2news gateway if crossposting with @bigapple.yi.org as mail2news. Added check to insure that usenet posts have a subject line. Added blank line to end of message body and after the .siglines to improve readability. Because Tonga does not allow setting custom 'From:' line, added error message if using Tonga as exit and a custom 'From:' Moved the "To do" list and changelog to their own files. 08/22/05 -1.1.6-Beta After message is sent, automatically un-tick the 'Include Surb' checkbox. 'Include SURB' was *using* the SURB that it was supposed to be sending. The conflicting variable use that caused it has been changed. Changed 'Reply with SURB' to 'SURB Reply', the shorter name improved the control layout. Added a second SURBfile select box for use with 'Include SURB'. Used color coding to associate selector boxes with surb function checkboxes. 'Include SURB' and 'SURB Reply' are now both working properly. Added Drive Selection to the config screen. Fixed Default values used in config screen when no mms.ini is found. Added 'please wait till dos job is done' msgbox to 'Create SURB' so that file selectors will update properly after create. 08/20/05 -1.1.5-Beta Added 'Autokill Sent Surbs' to options menu. If it's enabled, SURB files will be deleted after they are loaded into a message with 'Include SURB' Added final code that was left out of the 'First hop select' in the previous release. Adjusted the tab order so that it makes at least a little more sense. Added 'Clear Message' button to clear the message body area without clearing the rest of the form. Changed the 'Kill Temp Files' button to a button-style checkbox so that user can know when it's done when the 'button' pops back out. 08/15/05 - 1.1.4-Beta Adjusted announcement of Lcs Mail2news calculated address so that it stays quiet if 'Reply with Surb' is ticked. Added 'Options' to main menu Added 'Quiet Wipe' to Options. If enabled, file wipe operations will be done without status or error messages. Added 'Include SURB' checkbox. If ticked and a SURB file is selected, then surb file will be added to end of message after the .sig (if that's enabled.) Added 'First Hop Select' to allow choosing start of chain, added code to 'loadlasthops' routine so 'Update Servers' will refresh it also. 07/02/05 - 1.1.3-Beta Replaced "Update Servers" Button on main form. Replaced all file deletes with an attempt at an implementation of "U.S. DoD 5200.28-STD File Shredding scheme" in which the file being shredded is overwriten with hex$(x) where x is: 35,CA,97,68,AC,53,random and then delete the shredded file. This should be enough for the time being. I want to expand on this and also include a better RNG than what visual basic has. (Note for those who care: this is the ONLY use of VB's RND() function) 07/01/05 - 1.1.2-Beta Added "Queue Msg Only" button. If pressed, the message will be queued but not sent untill the queue is flushed. Changed "clear msg on send" to button style Updated the 'Using MMS' helpscreen. Still isn't a great help, but it'll serve for now. Changed 'Flush Queue' and 'Clean Queue' so that user can either use defaults or specify a server to act on. 'Clean Queue' can now specify age in days of oldest packet to keep. Added 'Create Dummy Packet' to the 'Mixminion' menu. It will create a dummy packet. If 'Queue Msg Only' is selected, then the packet will not be sent untill the next 'Flush Queue' Surbfile selector modified so that a surbfile can be selected WITHOUT having to tick 'Reply with surb' first. 06/29/05 - 1.1.1-Beta Removed 'Refresh Lasthops' button and combined it's function with the 'Update Servers' routine since both should be done at the same time. Added 'Mixminion' Item to main menu, Functions on it: 'Update Servers' (same as the panel button, which perhaps should be removed) 'Inspect Queue' Shows undelivered packets. 'Flush Queue' Attempt to deliver all packets in Queue. 'Clean Queue' Remove undelivered packets older than 60 days. 'Inspect Surb' Temporarily tick the 'Reply with Surb' checkbox and select a surbfile, then this function will show data about the reply blocks contained in it. 06/22/05 - 1.1.0-Beta Crosspost handling code in place. when using anon.lcs.mit.edu as the mail2news gateway, the newsgroups line will be automatically reformatted for use in the final gateway address. Error message generated if there is more than five newsgroups per posting. Added Error message if crossposting when not using the lcs mail2news. Removed Newsanon.ath.cx from mail2news gateway list because it appears to have been shut down at about the same time Parsifal remailer went down. 06/17/05 - 1.0.10-Beta Added ability for user to specify the last hop in the mixminion chain 'Refresh Lasthops' button reloads the 'Last Hop Select' combobox with current data. (This assumes that user has used 'Update Servers' within a reasonable period of time. If 'Last Hop Select' is set to 'Auto' then mixminion will just be told how many hops to select servers at random like before. Added checkbox 'Clear form when sending', Default is ticked, un-tick to leave the old message and settings in place so that it can be re-sent (presumeably to a different address or newsgroup). If it's un-ticked, the 'use sig' checkbox will un-tick on send because the sig is added to the message body just before sending, leaving 'use sig' ticked for more than one message would result in multiple copies of sig at the end of the message. In addition to combobox entries, now when program exits, the values showing for From, Newsgroup, Hops, Mail2news gateway, and Last Hop Select are saved in mms.ini as default values that will be loaded in on startup. Changes to 'reply to clipboard' routine to fix errors in handling the subject line (TL) 06/13/05 - 1.0.9-Beta On startup program was assuming that the 'surbs' subdirectory was there. changed to look for a placeholder file in the surbs subdir, if it's not found then create the subdir and the file. 06/11/05 - 1.0.8-Beta Changed several uses of 'Input' to 'Line Input' to stop commas from breaking inputs (TL) Changed M2N control so that the last selected m2n will persist untill changed or the reset form button is clicked. 06/10/05 - 1.0.7-Beta Removed a delete command I forgot to take out that was causing errors. 06/10/05 - 1.0.6-Beta Use of tempfile abandoned entirely. I found out 'App.Path' gives me what the tempfile was intended to do. 06/03/05 - 1.0.5-Beta In an effort to come up with a tempfile directory that most systems can deal with will now accept any of 'tmp', 'temp', 'homedir', 'windir', and 'winbootdir' that can be found. Added check to be sure news posts have an m2n selected. 06/01/05 - 1.0.4-Beta Changed tempfile usage to get either the "tmp" or "temp" environment variables assuming that there is a 'Set temp=Z:\dir' in autoexec.bat Changed hops selector from radio buttons to combobox. Range 2 to 20 hops. 06/01/05 -1.0.3-Beta Removed the Mail2news gateway radio buttons and replaced them with a combobox Added "@anon.lcs.mit.edu" to the list of Mail2news gateways and support for translateing the Newsgroups line into the "mail2news-YYYYMMDDemail@example.com" address format (using date$ to get the current date from the system clock) if lcs is selected as m2ngate. This makes 3 M2n's that encode newsgroup as part of the M2n address. Are there others?? On startup, write a tempfile in c:\windows\temp with the name of the program directory path. Delete when program exit. Should allow installing to any drive / path. 05/30/05 1.0.2-Beta Removed un-used source files from source directory. 05/30/05 - 1.0.1-Beta Fixed a typo that caused 2nd line of .sig to appear twice and skip the 3rd line. 05/30/05 Version 1.0-Beta Released for testing. 05/29/05 - 1.0rc9-Beta Added 'Debug' checkbox to main form. if checked show command line preview and the dos box with the send message command line. if not, then quiet operation. Added entries on config menu to allow entering up to 3 lines of text for a .sig which is saveed in the .ini file. Added 'Use sig' checkbox. (default NOT checked) If it is checked, the .sig text is appended to the message body after the customary dash-dash-space sig-separator line Added 'Beta' to version designation. When ready for public Beta release will drop the 'rc#' portion. Added 'Cancel' option to the 'Command line Preview' to allow aborting message. 05/29/05 - 1.0rc8 Added call to writeini sub after adding the new address to the to_addr combobox Updated config.frm to deal with current .ini format Changed "Newsgroups" to combobox and added save to .ini functions as the 'to and 'from' fields. 05/28/05 - 1.0rc7 Fixed error in build command line.. was adding an extra ".srb" to filename. Fixed handling of translating 'From:' or 'Reply-To:' in original to "To:" in reply / followup. It now strips all but actuall address for the "to" field but uses full 'user name <firstname.lastname@example.org>' format for attribution in quoted message. In 'reply to clipboard', added check to be sure clipboard was not empty. Added code to 'clearform' routine to de-select the checkbox and the surbfile select box. Fixed - redundant 'Re: ' was being applied to subject line. Fixed error in sending message. Was giving error anytime a SURB was not used. (TL) Changed "From" to a combo box and added the same functunality as the "TO" field has. User can now add frequently used values to the .ini file. (TL) Played with formatting of the 'Changelog' to increase readability (TL) 05/27/05 - 1.0rc6 Starting to fix the resize problem. The text box size now scales with the form as size is changed and minimum size established to keep controls visible and useable. Surb file select box now refreshes list when 'reply with surb' is ticked to make sure file list is current. this way dead surbs can be deleted and the list refreshed after creating a new surb without shutting down. Added Delete surbfile button and confirm delete. 05/26/05 - 1.0rc5 Replaced the 'use surb' button with a checkbox and file selection box to allow user to select surb file stored in c\mms\surbs. *note* once new SURB is created, it does not show in file box untill next time program starts.. Changed surbs creation and use routines to keep surbs in subdirectory of their own. Adjusted fonts and layout, set fields to use courier new 10pt fixed-width 05/23/05 - 1.0rc4 Added the beginnings of SURBs useage. It will eventualy need an overall SURBs manager. 'use surb' function to allow SURB as a destination. 'make surb' to allow creating SURBs. Mxminion cmd line building code adjusted to allow sending to SURB. Added 'decode clipboard' to decode SURBs replies. result is pasted into the message body area...(but not quoted) Adjusted cmd line building to skip 'from' address if one is not entered. 05/22/05 - 1.0rc3 Added 'reply to clipboard' function. it will get the text stored in the windows clipboard and automatically fill in the to, newsgroups, subject and references fields and then quote the message body, prepending ">" to each line. 05/21/05 - 1.0rc2 Added '-D no' to the command line it generates because it was failing because of an http 404 error while trying to do an automatic update-servers before sending a message. Added update-servers button. Shell commands set to vbNormalFocus temporarily for testing. 05/19/05 - 1.0rc1 First working version. manual entry of all fields and send msg using specified number of hops. can send to email address or to either bigapple or newsanon mail2news gateways.
