To make a message part an "attachment" (to modern mailers at least) you need
to add MIME headers. At a minimum
  Mime-Version: 1.0
in the main headers, and a
  Content-Type:
header, probably indicating multipart/mixed and a boundary string.

Then, around each attachment (i.e. after the boundary string) you add
headers describing that attachment; Content-Type:, Content-Transfer-Encoding:
(if needed) and possibly Content-Disposition: attachment (vs inline -
depending on how you want to recommend it be presented).

For all the MIME standards (RFCs), the best place to dig them up in on the
Internet Mail Consortium's web site (www.imc.org). They keep online indexes
of all the relevant RFCs, organized by categories.

If you'd like to see some samples, let me know. We can send you some sample
messages from our 3000 with various types of attachments.
