I am not sure what you guys are collecting as traffic but comparing dashboard to reports to mail manager doesn't match.
Screenshot 1: Top Spam countries dashboard. Total Traffic 12.4 KB
Screenshot 2: Top Blocked spam reason report. Take a look at antispam engine please. Mails 10, Bytes 7.6KB
Screenshot 3: Smtp Log for today with just spam filtered. Notice the total emails that are blackholed , total 10, bytes a lot more than 7.6KB.
I have no way of knowing the address verification totals since I can't see it in mail manager.
