Tak především se tam nepíše, jak by to mělo fungovat. Slashdot 13. srpna(!):
The idea is that a Centmail signature attached to a message would automatically reduce the message's spam likelihood; if enough people adopt Centmail, then receivers would be increasingly able to require a Centmail signature on mail, and killfile mail that lacks such a signature.
Takže asi tak. Je to v praxi blbost.
ještě perlička:
Problem is this: if you blindly trust Centmail, then it'll be worth it for spammers to pay to send email. Don't believe it? Check your physical mailbox.
Edit: ještě dodám tohle, protože je to naprosto výborný
