The most successful Internet protocols do not involve connections to hosts today. SMTP is a connection to a service and has been for two decades.

SMTP is also the least secure protocol that is in wide use; hop-by-hop forwarding without authentication of the message itself is a security nightmare. We have the same issue with flooding of random IP packets.
