Running DNS over Tor heavily mitigates the leak of meta data.  If you
run a decent gpg version on Windows and Tor is running, gpg will do just
that w/o the need for further configuration.  On Unix it is currently
only possible with a patched ADNS version (because upstream is pretty
slow to accept a patch to torify ADNS).

There are privacy aware mail providers who offer OpenPGP DANE.  For
example try my callsign @ posteo.net [1].  We are currently talking to
other mail providers to get them to deploy this or a similar https based
key location mechanism.

      auto-key-locate local,dane,pka,keyserver
