When attempting to send an encrypted message to multiple recipients,
mml-secure-message-encrypt-smime creates a "secure" mml tag contains a
separate certfile attribute for each recipient.  For example (with !
below replaced by #):

<!secure method=smime mode=signencrypt keyfile="~/certs/key.pem" 
certfile="~/certs/c1.pem" certfile="~/certs/c2.pem">

This gets parsed and eventually ends up in mml-parse-1.  In this block
of code:

       ((looking-at "<#secure")
        ;; The secure part is essentially a meta-meta tag, which
        ;; expands to either a part tag if there are no other parts in
        ;; the document or a multipart tag if there are other parts
        ;; included in the message
        (let* (secure-mode
               (taginfo (mml-read-tag))
               (keyfile (cdr (assq 'keyfile taginfo)))
               (certfile (cdr (assq 'certfile taginfo)))
               (recipients (cdr (assq 'recipients taginfo)))
               (sender (cdr (assq 'sender taginfo)))
               (location (cdr (assq 'tag-location taginfo)))
               (mode (cdr (assq 'mode taginfo)))
               (method (cdr (assq 'method taginfo)))

you can see that certfile is set by calling (assq 'certfile taginfo),
which loses all but the first certfile.  This causes it to be mapped
into this:

<!part sign=smime encrypt=smime keyfile="~/certs/key.pem" 

(again with ! replaced by #).

If you start off with

<!part sign=smime encrypt=smime keyfile="~/certs/key.pem" 
certfile="~/certs/c1.pem" certfile="~/certs/c2.pem">

and proceed to send the message, the message is encrypted with multiple
recipients as expected.
