===DSPAM Specific Statistics===
 
You can follow how DSPAM is doing by use of the dspam_stats command. Below is an example where I started the tagging process before training was complete. Here you can see that 4 emails reported as False Negatives meaning DSPAM claimed they were ham and SpamAssassin scored them as Spam (above spamlevel).
