My thoughts on antispam

02 09 07 - 01:49

Everyone knows spam today. There are estimations that it makes more than 90% of all email traffic. Judging by my personal spam collection, spam is on constant increase.

I have always filtered spam out of my inbox by hand. I played with almost all antispam technologies out there today and haven't found any to be perfect. They're either too hardware resource intensive (long list of daily updated regex rules) or too users' time intensive (manual training of statistical filter). Two tecnologies that made me think some more were greylisting and one-time email addresses.

The only way to stop spam is to increase the cost to spam, which basically means to decrease its efficiency. I came up with a concept that does this extremely well, while offering end user perfectly transparent and easy-to-get-rid-of-spam mail expirience.
