Sorry, but a web interface isn't an email gateway.
Transmitting an email via HTTP from a client computer qualifies
as gatewaying by my reading of the RFC.
That means you have to think my web browser is also an email gateway. I
don't see any reason to think it is more than a display transport.
The application running email isn't where the web interface displays
it any more than it would be if you display thunderbird in a remote
X session.
No, that's not correct at all. Using HTTP as a transport protocol
for email is quite different from using the X protocol to draw pixels
on a remote display.
How so? X does more than draw pixels, but neither X nor http know
anything about email or the contents of what they transport. That's all
up to the application at the other end - and it's why they are both so
useful.
But the RFC says nothing about remote displays and remote application
acccess, whether provided by ssh, X, or http(s).
The RFC defines a gateway as:
A "gateway" SMTP system (usually referred to just as a "gateway")
receives mail from a client system in one transport environment and
transmits it to a server system in another transport environment.
This describes webmail exactly. You type your email into a form in the
Web browser which transmits it over HTTP to the server. That's the
server "receiving mail from a client system".
The browser displays a form, but only the application at the other end
knows anything about the contents being mail. Which is exactly the same
scenario as if I typed it into thunderbird in a remote X window.
