Actually I just like to work as before the update. ;)

It worked perfectly for me. Now I have at least 30 mails in my unsure 
folder that are wrongly classified. Something is really not working as 
smooth as before here. Fortunately I have policyd-weight running on my 
mail server, otherwise I it might have been 500 or 1000 mails already.

I am considering setting ham treshold to +5 instead of +10. But I have a 
mail that has even been classified below +5 after learning. At least it 
should mitigate the problem somewhat.

Just want things work as quickly as possible, cause I had a bit lot of 
issues to debug. Okay, I run Debian testing/unstable and I compile my own 
quite recent. But at the moment I long at least a bit for Debian Lenny 
with bog standard stuff ;).

Ciao,
