  24       <div class="date">10th November 2014</div>
  25       <div class="body"><p>The right to communicate with your friends and family in private,
  26 without anyone snooping, is a right every citicen have in a liberal
  27 democracy.  But this right is under serious attack these days.</p>
  28
  29 <p>A while back it occurred to me that one way to make the dragnet
  30 surveillance conducted by NSA, GCHQ, FRA and others (and confirmed by
  31 the whisleblower Snowden) more expensive for Internet email,
  32 is to deliver all email using SMTP via Tor.  Such SMTP option would be
  33 a nice addition to the FreedomBox project if we could send email
  34 between FreedomBox machines without leaking metadata about the emails
  35 to the people peeking on the wire.  I
  36 <a href="http://lists.alioth.debian.org/pipermail/freedombox-discuss/2014-October/006493.html">proposed
  37 this on the FreedomBox project mailing list in October</a> and got a
  38 lot of useful feedback and suggestions.  It also became obvious to me
  39 that this was not a novel idea, as the same idea was tested and
  40 documented by Johannes Berg as early as 2006, and both
  41 <a href="https://github.com/pagekite/Mailpile/wiki/SMTorP">the
  42 Mailpile</a> and <a href="http://dee.su/cables">the Cables</a> systems
  43 propose a similar method / protocol to pass emails between users.</p>
  44
  45 <p>To implement such system one need to set up a Tor hidden service
  46 providing the SMTP protocol on port 25, and use email addresses
  47 looking like username@hidden-service-name.onion.  With such addresses
  48 the connections to port 25 on hidden-service-name.onion using Tor will
  49 go to the correct SMTP server.  To do this, one need to configure the
  50 Tor daemon to provide the hidden service and the mail server to accept
  51 emails for this .onion domain.  To learn more about Exim configuration
  52 in Debian and test the design provided by Johannes Berg in his FAQ, I
  53 set out yesterday to create a Debian package for making it trivial to
  54 set up such SMTP over Tor service based on Debian.  Getting it to work
  55 were fairly easy, and
  56 <a href="https://github.com/petterreinholdtsen/exim4-smtorp">the
  57 source code for the Debian package</a> is available from github.  I
  58 plan to move it into Debian if further testing prove this to be a
  59 useful approach.</p>
  60
  61 <p>If you want to test this, set up a blank Debian machine without any
  62 mail system installed (or run <tt>apt-get purge exim4-config</tt> to
  63 get rid of exim4).  Install tor, clone the git repository mentioned
  64 above, build the deb and install it on the machine.  Next, run
  65 <tt>/usr/lib/exim4-smtorp/setup-exim-hidden-service</tt> and follow
  66 the instructions to get the service up and running.  Restart tor and
  67 exim when it is done, and test mail delivery using swaks like
  68 this:</p>
  69
  70 <p><blockquote><pre>
  71 torsocks swaks --server dutlqrrmjhtfa3vp.onion \
  72   --to fbx@dutlqrrmjhtfa3vp.onion
  73 </pre></blockquote></p>
  74
  75 <p>This will test the SMTP delivery using tor.  Replace the email
  76 address with your own address to test your server. :)</p>
  77
  78 <p>The setup procedure is still to complex, and I hope it can be made
  79 easier and more automatic.  Especially the tor setup need more work.
  80 Also, the package include a tor-smtp tool written in C, but its task
  81 should probably be rewritten in some script language to make the deb
  82 architecture independent.  It would probably also make the code easier
  83 to review.  The tor-smtp tool currently need to listen on a socket for
  84 exim to talk to it and is started using xinetd.  It would be better if
  85 no daemon and no socket is needed.  I suspect it is possible to get
  86 exim to run a command line tool for delivery instead of talking to a
  87 socket, and hope to figure out how in a future version of this
  88 system.</p>
  89
  90 <p>Until I wipe my test machine, I can be reached using the
  91 <tt>fbx@dutlqrrmjhtfa3vp.onion</tt> mail address, deliverable over
  92 SMTorP. :)</p>
