Or on another plugin/solution to support mail encryption/signing?
OpenPGP for Roundcube via JavaScript: https://github.com/qnrq/rc_openpgpjs
That's a start but unfortunately only works on text parts but not for attachments. But in terms of architecture, a purely client-side encryption/decryption is the preferred and most secure way.
Please find a summary about the current situation and the proposed next steps to get that done: http://trac.roundcube.net/wiki/PluginRepository/Encryption
Regarding S/MIME, GnuPG is also supposed to do S/MIME but I'm not sure whether the OpenPGP.js has plans to add that too.
We'd much appreciate any contribution on this. If anybody decides to work on the OpenPGP.js approach, please get in contact with the author of the rc_openpgpjs plugin.
Best, Thomas
