Hi,
I'd like to share some of my private notes about
requirements a solution must/should fulfill:
- must work everywhere on the world, in every legislation
- must work with every spammer, regardless of age, etc.
- must work with every recipient, regardless of age,...
- must work even if spammers know all details
- must fulfill Shannon's Maxim (Attacker knows cryptographical methods)
- must fulfill Kerckhoff's Law
- must be robust
- must not require to be updated often
- must work with any language
- must work with encrypted messages
- must be easy to maintain
- must work for the dummy user
Any comments or objections?
- must be as simple as possible in implementation (KISS)
- must be free of restricted IP (as in intellectual 'property')
- must limit the load increase on the network to a minimum (think
low-speed links, pay-per-packet links, etc)
- must not increase the cost of email for users (so no pay-per-mail)
