Spam and Sent Items
I'm using the SpamBayes anti-spam filter. It's an Open Source "Bayesian anti-spam classifier written in Python", and I've found it to be excellent!
So I've counted up my total e-mail produciton for 2003 -- 13,544 sent items between work and home. And that doesn't count mail sent on vacation, from consulting gigs, or HotMail / Yahoo!!
