Hi,
I'd like to know how to build an SMTP multipart message in the correct order so that it will render correctly on the iPhone mail client (rendering correctly in GMail).
I'm using Javamail to build up an email containing the following parts:
- A body part with content type "text/html; UTF-8"
- An embedded image attachment.
- A file attachment
I am sending the mail via GMail SMTP (via SSL) and the mail is sent and rendered correctly using a GMail account, however, the mail does not render correctly on the iPhone mail client.

Even if you can't assist me with this, I would appreciate it if any members of the forum could forward me a (non-personal) mail that includes inline images (not external hyperlinked images though). I just need to find a working sample then I can move past this.
Thanks,
Chris.
