Hacking it in? Probably easy.

Doing it right? Very hard. Comparable to PGP clearsigning and that one 
is already ubiquitous in KMail. Look how many files #include <kpgp.

There is a reason why uuencode and clearsigning are both deprecated: 
Combining such things is combinatorically infeasible.

Outlook can be configured to not send uuencoded mail, or at least send 
them as MIME attachments with Content-Transfer-Encoding: x-uuencode, 
which we support for reading.

You can extract the attachments from uuencode-mails by piping them 
trough a script that calls uudecode and writes the results to a 
attachment-dump directory with a constructed name. Search the 
kmail@kde.org archives. Or use KNode.

This feature has _very_ low priority, and a steadily decreasing one, 
too, as uuencoded mails get more and more uncommon. My personal barrier 
for patch-acceptance is very high with this one. You'd need to design, 
write and refactor quite a bit of code to provide generic hooks for 
abstracting the various just-do-it-inline methods, such as PGP 
clearsigning, inline uu-, yenc- and base64 encoded "attachments", geek 
codes, etc. But _if_ you've invested that much energy into it, rest 
assured that I'll help you get it polished for inclusion.
