Good suggestion.

Let us think why we do not have so severe spam problems in the real mail system (paper mails, not email). Because of postage. Email spammers send emails without paying postage.

I am thinking if we can imagine that emails should be added with electronic postages prior to being submited to the Email server. I think, with so developed computer technology we have, it is not a dream. Although this comport may incur widespread objections, I still believe E-postage could be a prospect of our future email system.
