Years and years ago there was some talk of having a &quot;postage stamp-like&quot; fee to send and receive e-mails.  Enforced by the recipient&#x27;s server, I guess.  That way spam and low-quality memo-writing would be discouraged.  Instead of monetary points it could be karma points or something.  This didn&#x27;t go anywhere 10 years ago, but maybe the time is ripe for it now.  People are a lot more comfortable with micropayments and there&#x27;s a lot better infrastructure for the necessary communication&#x2F;negotiation between sender&#x27;s and recipients&#x27; email.
