Hi Lars, Shenghuo!

I discovered your email adresses in the header of `message.el` or
`mml2015.el`, respectively, in the Emacs distribution (V23.1.1).
That's why I'm writing you.

I found the following problem. When I GPG-encrypt multiple mails with
the Emacs machinery for different recipients the key used for the
first encryption is used for all mails - regardless of their
respective recipients. As you can imagine this is very annoying
because all but the first recipients get mails they can't decrypt :-( .

I tracked the problem down to the function `mml2015-epg-encrypt`.
There is a

       (let
        ...
 	(recipients (message-options-get 'mml2015-epg-recipients))

which via `message-options-get` fetches recipients from
`message-options`. Since `message-options` is global and seemingly the
`mml2015-epg-recipients` field is never cleared I get the results from
a previous encryption. This is probably the reason why only the first
key is used as described above.

I solved the problem for me by making `message-options` buffer local -
which seems the right thing to do anyway.
