Hello Tempest,

Basically Greypony has been mostly configured, but I'm running into
some issues doing transparent proxying with Postfix and the edge MTAs.
 I don't want to store any of the mailboxes on the edge MTAs at all.
All of the mailboxes must be stored on Tor in order to assure security
and anonymity of sources.  I'm hoping that the code that Lunar has
that Ruby code that'll allow the configuration of using querying DNS
via TCP to prevent DNS leaks outside of Tor.

Of course, if anyone has any suggestions, I'm more than open to them,
please - I would like to consider this a group effort.

For those who don't know - Greypony <http://www.greypony.org> is a Tor
based hidden email solution that allows users on Tor to send emails to
the public Internet from within the Tor network, send emails to other
Tor users, and allows public Internet users to send emails to Tor
users.  The goal for the service is to have built in GPG encryption,
IMAP, webmail, and all sorts of other goodies.

The Internet facing MTAs (the MTAs on the Public Internet) just run a
MTA, do not perform any logging whatsoever, and just forward emails to
the Tor dataserver.  The opposite occurs, the Tor dataserver sends an
email to the MTA and it forwards it on the the Public Internet.
Again, no logging is performed on the Tor dataservers either.  There's
no way to recover passwords on the dataservers.

Preferred authentication would be Certificate based authentication
(certificated would be generated) and again, GPG would be used to
ensure proper security.

If there's any suggestions, or any questions, please let me know.
