That was the information I was looking for. I knew it already from using
bogofilter -h but I wanted it to be confirmed before I start using it.

BTW, in order to prevent that ham is accidentally detected as spam and
thus blocked I wrote a nice system that asks the sender to confirm the
email and then unblocks it (I store all spam in a mysql db and trash 
entries
after a week or when they are confirmed). To prevent useful feedback to
spammers I send out confirmation questions from a configurable extra 
account
(i.e. admin at pardeike.net for spam received at andreas at pardeike.net). If 
I
get a bounce or error message I can classify the email as spam 
directly. If
I get an real answer, I reregister it as ham. After a week, I register 
it
as spam. This works flawless because it also prevents mail loops (the 
admin
address never answers to email that it receives - it only checks for 
valid
confirmations).

I am thinking of making the whole system public and creating an 
installable
solution from it. Is anybody interested?
