Re: Feedback on Hypertext Mail Protocol (a.k.a. Stub Email)

You're right, the 1000 request thing isn't such a good idea, or else 
it would probably already be popular with forms of spam that are 
currently susceptible to that. In any case, I think spammers would at 
least lose out indirectly because people would be more incentivized to 
fix compromised servers and not provide free service to spammers.
