To put it shorter: I want the internet to be able to transport *only* 
emails with one verifiable origin and one verifyable destination. 
Everything else (more than one destination per send), is to be blocked 
actively. Mailing lists could be run by appointment with the 
administrator of the originating server. There will be exactly one 
destination delivered to per mail from/rcpt to/data session. The data in 
mail to: and To: will coincide. The data in From: and mail from: will 
coincide. Bouncing, mailing list issues, etc can be handled using other 
headers, like Reply-To etc etc.
