What do people today think of the SMTP RFC's current requirement that
mail programs and servers must not under any circumstances change or
delete Received: headers? Is exposing sender IP addresses to any
attacker who can view e-mail headers, for the purposes of preserving
trace information, really worth it when weighed against considerations
like security and privacy?
