[Spambayes] Why was this e-mail's body ignored?

[David Leftley]

I was surprised to see the message below appear towards the lower end
of my "possible spam" range - but looking at the breakdown of how the
message was classified, it turns out that spambayes is ignoring the
entire message body.

What is it about this message that makes spambayes think it has no
relevant content? Is it simply that we don't try to handle
multipart/alternative messages?

David.
