Bogofilter seems to not be working

[daniel]

I have set up bogofilter with the procmail recipies in the man page:

:0fw
| bogofilter -u -e -p

:0e
{ EXITCODE=75 HOST }

:0:
* ^X-Bogosity: Yes, tests=bogofilter
spam-bogofilter


Initially I was getting spamicity readings such as 0.415000, 0.000002, spamicity=0.081142.  Now however all my new mail has a spamicity of 0.000000 despite the fact that I think some of it is blatant spam.  I have 
 bogoutil -w ~/.bogofilter .MSG_COUNT
                       spam   good
.MSG_COUNT              180    442

so far and bogofilter still has not filtered anything into spam-bogofilter.  I am wondering if it is working correctly or if it is failing and if there is something I can do to check?
