[Spambayes] Configuring Spam Folder

[Brian Gatfield]

I have enabled Spambayes and have trained Spambayes - but I cannot set the
location of the folders where the certain and unsure spam is to be moved to.
I can define the filters such that the moved to folders are defined but when
I back out of the Define Filters window, the location of the folders for the
spam change to <unknown>.   I cannot set the folders and everytime I try to
use Spambayes, I get a message stating I must configure the spam folders.

How?
