Well, I don't see anything on the web about this B2 format. My guess
is it's a proprietary format which their system uses. And as they say
they will convert mime to their format.

If you haven't already, get PEAR's Mail_mime package. You can make an
e-mail with only text or only html or both and attach files easily.
Then you can use PEAR's Mail package to send it. It's very simple.
