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
   transmits it to a server system in another transport environment.

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.

Gmail has made its own bed.  I can't trust anything coming from Gmail, so I
reject it.

Anyway... I guess this is a religious issue.  I know I'm right, just as
I know that emacs is the ultimate text editor. :)
