SMTP (RFC 5321) makes the distinction between relay and
gateway, where I read the latter as matching the Mediator
construct in email-arch. And it is rather specific about the
functional distinctions. What you are describing doing
clearly falls into the camp of gateway/mediator.
And, FWIW, from a RFC 5321/SMTP perspective, any Message
Submission (RFC 4409) server clearly falls into Dave's Mediator
category. If I recall, Randy and I spent some time trying to
get the terminology in 2476 right to avoid getting crossways of
the Gateway/Relay distinction.
