After 55 months of tracking spam on Yahoo I think I will finish my tracking of the mail. Over the time I received almost 19,000 emails of which less than 7,000 were legit. Over this year the rate has improved to almost 70% legit mail. Spam and phishing emails are still a problem, but, with the various providers working on their filters and the authorities shutting down the spammers things are improving.
2005 - Legit mail = 1000 which was 50% of my total mail
2006 - Legit mail = 1700 which was 22% of my total mail
2007 - Legit mail = 1800 which was 31% of my total mail
2008 - Legit mail = 1500 which was 69% of my total mail
2009 - Legit mail = 1000 which was 70% of my total mail
