Re: Why spam is a problem.

There must be a secure method that would allow a receiver to verify whether 
or not the sender actually exists as a user on the mail server for the 
domain the e-mail is coming from.

this is already possible.  it is not sufficient.

the recipient doesn't care whether the sender address exists, the recipient
cares whether he gets spam.
