Add a header when sending, if signed

[Charles Jie]

Hi,

    I want mutt to add a header 'X-PGP-Key' if the message is signed
    (from 's' command in pgp-menu).

    I tried to use 'send-hook' as following:

        send-hook ~g 'my_hdr X-PGP-Key: http://wwwkeys.us.pgp.net:11371/...'

        while '~g' means to match "cryptographically signed messages"

        The intention of this is to "Add the X-PGP-Key header if this
        message is signed before sending".

    Of course this configuration does not work, because:

        1. The send-hook is triggered when composing the message.

        2. The send-hook only sees the pattern as about recipients, not
           about anything else.

    Do I have any suitable 'hook' to do it?

        We can only sign it after the message is finished, right?

        So I need a hook which will be triggered when I send the
        message (after I decided to sign it). This hook will check if
        it's signed and run a my_hdr command to add a header about
        keyserver info.

    Any clue?

        (Though I could always add this header even I don't sign. I
        still hope to keep the message cleaner and reduce internet
        traffic.)

best regards,
charlie
