We rely so much on email, and yet it's still largely a blackbox. We type
into the box and hope the other side gets our message. Amazing how so
much has changed on the Internet, and yet so little has changed.
Last week I migrated our 5 year old Postfix mail server to Slicehost, and took the opportunity to install some spam fighting tools that weren't available 5 years ago. In the process, I noticed that my primary email account's junk folder went from adding 1000+ spam emails a day to less than 20. I hesitated to blog about it but the results keep getting better after 1 week.
