My Ongoing Fight Against Spam
It is time for another SPAM update! I posted the first one on November 29, 2006. At that moment I received an average of 1.346 spam messages per day and I just started using SpamSieve, for two days, to filter out all of it.
It has been 39 days since I started using SpamSieve. Here are the results:
Filtered Mail
1.613 Good Messages
36.531 Spam Messages (96%)
952 Spam Messages Per DaySpamSieve Accuracy
69 False Positives
41 False Negatives (37%)
99.7% Correct
My daily average has gone down from 1.346 spam messages per day to only 952 spam messages a day. My accuracy improved from 99.5% to 99.7% and I received a total of 36.531 spam messages! Incredible.
I hope to get the accuracy of SpamSieve up to 99.9% because I still often have to check the spam folder to see if I havent lost any good mail in there.
Will I ever stop getting spam?
UPDATE: Techcrunch reports getting their millionth comment spam today. I didn’t even count those yet! Akismet has caught 1,389 spam comments and trackbacks for me.

My solution to spam is to do greylisting: http://greylisting.org/ . It works near-perfectly against spam, with in theory no false positives, although
it has (to me, minor) drawbacks. It does have to run on the machine(s) receiving the mail though (mxes). I don’t have exact numbers but it’s made my mail from near-unusable (after being scanned by spamassassin and a tuned bogofilter) to near-perfect for the greylisted address.
