If you already get the MIME structure, then I guess you have struct message_parts. You could do it similar to the way IMAP does things:

   1          TEXT/PLAIN
   2          APPLICATION/OCTET-STREAM
   3          MESSAGE/RFC822
   3.HEADER   ([RFC-2822] header of the message)
   3.TEXT     ([RFC-2822] text body of the message) MULTIPART/MIXED
   3.1        TEXT/PLAIN
   3.2        APPLICATION/OCTET-STREAM
   4          MULTIPART/MIXED
   4.1        IMAGE/GIF
   4.1.MIME   ([MIME-IMB] header for the IMAGE/GIF)
   4.2        MESSAGE/RFC822
   4.2.HEADER ([RFC-2822] header of the message)
   4.2.TEXT   ([RFC-2822] text body of the message) MULTIPART/MIXED
   4.2.1      TEXT/PLAIN
   4.2.2      MULTIPART/ALTERNATIVE
   4.2.2.1    TEXT/PLAIN
   4.2.2.2    TEXT/RICHTEXT

So you get the root message_part. Its first child is "1", second child "2", 3rd child "3", 3rd child's first child "3.1", etc.
