confusion over headers and spam marking

Hi, 

I have dccm installed and X-DCC headers are being written but I am a
little confused over how spam is marked. will it have "bulk" before
the scores all the time? In my dcc_conf I have the default 

#   add X-DCC headers.
DCCM_LOG_AT=5
DCCM_REJECT_AT=  

I am also starting dccm with -d and writeing to local5 but there isn't
all that much info in the log file... can I write a log that shows
rejections and how each mail was marked or anything?

I just need to sort this out because I'm not sure if dcc is really
doing its work. 

We have no dccd because we are under 10000 emails per day. 

thanks!
