SMTP is definitely not a p2p protocol in most corporate environments. In ou=
rs, all email (even ones that you would think should be host2host) go to a =
central "smarthost" that processes the mail, and archive it for compliance.=
All internal to external and external to internal email is tightly control=
led and only goes through a very specific route.
Again, big difference between a univerisity or ISP environment and a corpor=
ate one.
