My boss just got a short email message that was classified by Exchange as
UCE (SCL=8). He asked me why it was classified as spam. I looked at it, and
I don't know either. I was wondering if anyone else could give me a hint as
to why this simple text message got an absurdly high SCL. SpamAssassan
gave it a rating of 0.0 This is what the headers say:

It's from Australia. Everyone knows that all mail from Australia is spam.

Seriously, Microsoft's algorithm is a black box and a closely guarded trade
secret.
