The RFC defines a gateway as this:
A "gateway" SMTP system (usually referred to just as a "gateway")
receives mail from a client system in one transport environment and

Unfortunately, a "transport environment" is not defined by the RFC.
I consider submission via HTTP to be sending mail over a transport
environment. I think it's a reasonable interpretation, but alas... the
RFC doesn't say.
We are obviously not going to agree here but a few more data points:
using the OWA interface (outlook web access) to an exchange server does
not add a Received: header for the browser client IP. Likewise when
sending from outlook 2003 or 2007 (much more believable as mail clients)
through exchange, the first Received: header is the server's.
