2009 Spam
Since I switched to Google for handling my email I don't have as fine grained tracking of spam as I did in years past. My first line of spam defense is Postini which caught 43,683 spam messages for 2009. I get very few false positives from Postini so that number is about spot on. My GMail spam folder currently holds 406 spams messages received in the last 30 days. If I do a rough calculation, I'd say GMail caught another 3,263 spam messages. Postini drops certain spam messages into the bit bucket before I see any trace of it which contributed to only 45% of my email for 2009 being spam. The number of spam messages a day though is marching upwards. Minus a few drops when a spam botnet is shutdown the trend for the year isn't pretty as the graph below shows.
