autoselect GPG key for signing by group

autoselect GPG key for signing by group

[Hikaru Ichijyo]

I would like to sign/decrypt messages using one key in some groups,
using a different key in other groups, and in still other groups, not
sign/decrypt at all.

I have most such per-group preferences for other non-encryption related
things setup in my ~/.gnus.el using the gnus-posting-styles mechanism,
but since that seems to mostly just set variables (and not run
commands), I'm not really sure what I would put there to do something
like this.

Most people seem to invoke GPG signing like this (assuming they only use
one key everywhere, always):

(add-hook 'gnus-message-setup-hook 'mml-secure-message-sign-pgpmime)

How would I setup my key selection to depend on what group I'm in?

There is some useful information in the thread "Maybe encrypt message ?"
in gmane.emacs.gnus.general (I don't find any archive on the web...)

This might work: Keep the default (nil) for
mml-secure-openpgp-sign-with-sender and set
mml-secure-openpgp-signers via posting styles.

I’m using the piece of code for message-header-setup-hook described
