Yeah, I read up on it some more after responding.

However, from some things on support.microsoft.com, such as:

http://support.microsoft.com/support/kb/articles/Q241/5/38.ASP

[oh hey, that's even one of the ones you mentioned], it seems that
TNEF may be the key to being able to parse meeting requests and some
other "special Outlook data that require TNEF rather than regular file
attachments" [sic].

At any rate, if we want to be able to "interoperate with" (read:
"infiltrate") Outlook/Exchange sites, we need to play the TNEF game
at least a little.

No, it says "use MIME instead of uuencoding (to encapsulate the TNEF
data) if the recipient supports it".

Yeah, I was planning on making the formatter only pick the TNEF
version if there wasn't a plain or HTML version. (Someone here got a
message the other day with a single TNEF part and no readable
version.)
