You post the message body? I thought you'd post only the session-key. We
can get the body from IMAP, so I wouldn't post it.

This calls for a PR to Crypt_GPG library.

I think it should go through the message parser. So, load the message as
before with all enigma's hooks parsing the message but where decryption
is supposed to be executed use the session-key instead of key/password.
I suppose you'd have to store the session-key in Roundcube session for
some time, as we normally do with private keys passwords.
