Date: Thu, 13 Sep 2001 13:40:58 -0400 From: Christopher Ferris <[email protected]> AN SMTP node is NOT an MSH node. It is not part of the equation. The MSH nodes that are communication via SMTP are the ones that adopt the RM protocol of retries in the absence of an Acknowledgment. The SMTP nodes are incidental. I agree. An SMTP store-and-forward mailer is *not* an MSH IM. SMTP is at the next layer down, which is an entirely different matter. From the vantage point of ebXML MS, SMTP store-and-forward mailers are just part of the vast, foggy, unreliable cloud labelled "Internet". From our point of view, if an SMTP mailer drops a message, that's exactly the same as a message being "lost in the Internet" while in transmit between one MSH and another MSH. What's needed is a use case that's unreliable but must act at the ebXML MS level of abstrction, i.e. it understands and interprets the data formats described in the MS spec. An SMTP mailer just takes the packaged message and passes it along, treating it as opaque.
