Took out smime, since this discussion has nothing to do with it.
Modern Word and Excel files are in ZIP container formats. Therefore,
they are already compressed. [Looks like Paul Smith already posted about
this.]
Oh, right, forgot about that.
It's looking to me like there are two places where CDAT might be useful.
One is to squeeze base64 encoded stuff back to about its original size.
The other, since the compressor is deliberately not reset between
messages, is when you send approximately but not quite the same message to
several people in the same session, e.g., different text with the same
attachments. Imagine you're an ESP sending tarted up mail with lots of
images, and each recipient's name is spliced into the text of his message.
