[horde] Horde WhiteList doesn't stop SpamAssasin?

[Al Franz]

I have a problem where mail is going to my Spam Folder in Horde even though
the FROM address is on the WhiteList.  Look at this following message,which
was blocked by SpamCop due to a bad MSN Hotmail server.  The FROM address
was on my WhiteList but it still went into the SPAM folder.  Should this of
happened?

Thanks, Al
