As my statistics are posted in fixed format, I often copy the post of the previous day/month into a new post, and change only the numbers and charts. Today, when I tried to compose the first monthly statistics for 2011, I found out that the ending time of all my monthly detection periods last year had been incorrectly written as "2001." It took me some time to fix this for all the 12 monthly statistics reports of 2010.
detection period: 2011-01-01 00:00 - 2011-01-31 23:59 UTC

recipient count of blocked spams: 272619859
