 Hi,

 I have multiple subkeys on my GPG key and I'm not finding a way to let
 enigmail  use a specific subkey.


 What's the best way to use enigmail with subkey?

Enigmail has precisely zero code that second-guesses GnuPG.  We don't 
ask for passphrases: we let GnuPG decide when and how to ask for 
passphrases.  We don't ask you which symmetric cipher or hash to use: we 
let GnuPG decide which to use.  Anything GnuPG has clearly decided is 
its responsibility, we don't touch.  That's been a guiding principle for 
many years, it's worked well for us, and this close to the end of 
Enigmail I don't expect we'll be changing it.


Choosing a subkey is GnuPG's responsibility, so -- we don't touch it.

It is possible to override GnuPG's subkey selection algorithm by setting 
flags in gpg.conf.  It is definitely not recommended.

IIRC I've used the Preferences -> Advanced -> Additional parameters for
GnuPG setting to specify a --local-user for this.

(Rationale: for a key-signing event I wanted to send someone a proof
that I owned the master key, not just the subkey.)

No, that's not what I said. You can't /select/ a /specific/ subkey with
Enigmail. Everything else is fully supported. I.e. gpg chooses an
appropriate subkey for whatever operation is performed.

No.

Same.

Okay, so to use enigmail, only one subkey for the sign capability and
one subkey for the encrypt capability is allowed.

Is there any plan to add this functionality to enigmail?

What is the state of subkey with regard to Thunderbird when support for
GPG will be built-in?

Enigmail does not support that.
