The function message_create_attachment only creates an attachment, it
does not actually attach it to another message. To attach a message,
use mime_add_part function. The scenario is:

1) Create a MIME object using mime_create
2) Create your attachments (either directly or using one of
the functions from attachment.c) and append them to the MIME
object using mime_add_part().
3) Call mime_get_message(). It will return the message object
associated with the MIME object. This is what you need: a message
with all the attachments included.

See the following sources for examples:

libsieve/actions.c        build_mime() function at line 126
mh/mhn.c                  edit_mime() at line 2156.

I doubt if it would be a reasonable thing to do. Attachments should
be added to the MIME object, which helds all the information necessary
for the proper encapsulation. Message_t simply lacks the necessary
mechanisms, and it shouldn't have them, anyway.
