Comment:

 Emails with content type other than multipart/alternative does not get
 parsed properly by wp-mail.php.

 If you examine the code (line 43), it only handles "multipart/alternative"
 explictly, and never gets the boundary string properly.

 Also, it assumes that the text/plain section is the first message section
 (line 109) but it might not necessary be true.

 As such, with emails encoded in other multipart formats, e.g.
 multipart/mixed, wordpress will dump the undecoded content of the mail
 into the blog post.

 I would suggest incorpration of a MIME decoding library to properly handle
 MIME decoding. What I did was write a quick hack for it.
