The definition of "attachment" is not as clear as you would think. For
example, we tend to think of MIME components whose type is text/* as
not being "attachments", but sometimes they can be (e.g. if I sent you
a txt file). The same problem exists with pictures in GUI mailers:
they can display the picture, or treat it as a file, or both. This is
what RFC 2813 (the Content-Disposition header) is designed to help
with. And when multipart/alternative is involved... it gets nutty.

Here's a wacky message structure my mom sent me (using Apple Mail):
I 1 <no description> [multipa/alterna, 7bit, 653K]
I 2 |-><no description> [text/plain, utf-8, 2.0K]
I 3 `-><no description> [multipa/mixed, 7bit, 651K]
I 4 |-><no description> [text/html, quoted, windows-1252, 3.0K]
I 5 |->Typeface Ideas.pdf [applica/pdf ...]
I 6 `-><no description> [text/html, 7bit, us-ascii, 0.2K]
I haven't set up attachment detection properly, so %X says this
message has 0 attachments.
Details of how this works and why it's hard are here:

It *is* (or at least, can be) compliant.
