What was the "official" answer according to the answer sheet published by the Board of Studies? They would have accepted angles between 355 and 365 degrees.
If you consider how thick the lines were, it could be a bit less than 360:)
Why not?
You have whitelist based programs like TMDA and ASK that do something like that but you need user action.
If you could integrate to servers and clients, you could have this more transparent (and more effectively fighting spam).
The idea is simple:
1- The email is sent. It stays on the queue.
2- A challenge is sent back (in case the origin is not already in the whitelist).
3- The origin is then authenticated sending a reply to the challenge...
That's it.
(a bit the same TCP does to IP... Make it trustable.)
PS.: Of course the spammer could legitimate his origin, but at lease you can add (and identify)him more easily in the blacklist.
My car runs with alcohol there and the tank is the same (only a bit less autonomy...about 15%) And Brazil has cars running on alcohol for about 20 years or more...

Google should get Linux code and fight back developing an OS !!!
Next time try inserting the #2 pencil in your ears. (Crayons are more confortable though). It also works well, and your computer keeps working...
