feature request: Sign and encrypt emails using OpenPGP

[APachLv]

Dear Team.

Please add Sign and encrypt emails using OpenPGP per user and from domain.

This requires PGP/GPG on server side, since the JS version has major issues.

You can use it client-side and copy it to email.

Built-in OpenPGP support would be fantastic for increased security and sender identity confirmation. The OpenPGP code is open source, and it's well-implemented in Thunderbird, for example. Installing modules or libraries supporting a GnuPH or GPG server is no problem, but changes to the GroupOffice mail module would have to be made by the team. I am joining the reques @APachLv :) . @lonesomewalker idea copying emails from another program isn't a solution, but a terrible prosthesis :(

Feel free to start doing it. I have given by 2c to this, because i already tried with the js version and this is pretty nasty. Therefore it has to be fully supported serverside...
