The number of emails reported as blacklisted seems excessively high.  After adding IP addresses to the blacklist, the total number of emails received does not seem to have changed significantly, yet the number reported as blacklisted has got extremely high - higher than the total number of emails received (including spam).  I find it hard to believe spam increased so considerably at the same time as I happened to add their IP address to the blacklist.

Also the white list numbers - these appear even with no entries in the white list.  What are these? I guessed it must be the total number of emails getting through which are not black listed, but I can see from mail reports that this is not correct.
