Mailvelope GnuPG Integration

Hi all,

I am trying to setup my roundcube client to encrypt and sign emails automatically using my gpg keychain on my computer. I have installed the mailvelope plugin and set it to prefer my gnupg keychain. In roundcube, I have enabled api access to mailvelope for my domain. The state of the "Use Mailvelope main keyring" does not seem to change anything.

If I click the "Encrypt" button above my message, then the mailvelope editor becomes embedded and I can send an encypted email. However, If I do not have the public key for a recipient, I am unable to only sign my message via this method, which should be possible.

If I use the toggles on the right of my message, then when I click send, I get an error saying that there is no private key. I suspect this is because mailvelope shows my "Main keychain" as empty (which is being used by roundcube) and my "gnupg keychain" as preferred.

I suspect that I have misconfigured either roundcube, mailvelope or both, but not sure what I need to do to get this to work. Any advice would be greatly appreciated.

Cheers,
Daisy
