[Spambayes] subject not modified

[Rodney Green]

Hello,

I just setup spambayes. I want it to modify the subject of messages and add
the classification to the beginning of the subject. I set this up in the
configuration but no modification is happening. I do see the x header added
with the classification when I look at the headers. I'm using Outlook
Express and wish to have the subject modified so I can filter it using the
rules. Any idea of what might be wrong?

Thanks,
Rod
