Subject: RE: [ebxml-msg] SMTP support in ebMS 3.0?

Sacha, I believe your question is addressed by the main conformance profile. Whether SMTP is first class or not, this is not a concept that should be directly addressed by the core spec itself, but rather by one of the conformance profiles which are separate documents. If I am not mistaken, I think the main conformance profile supports SMTP. Plus as David said, the pull feature in ebMS-3 is also addressing the issue you are describing.

In your scenario - the SMEs only have issues receiving ebXML msgs - not sending.


Also - now with the new staged delivery "pull" mode - remote clients could defer delivery until they announce their presence and "pull" queued messages waiting for them.


Seems to me that the v3.0 features actually significantly reduce the need for SMTP at all here.


In fact we could probably create a pMode for this and template of CPA + "pull" message sample - so the v3.0 server would place messages in a queue and then await a request to deliver them.


Now if an SME is sending a message to another SME - then those should be routed thru an intermediary ebMS that guarantees service availability to act as the delivery server.

Hi ebMS Team
One question I have for the TC:
"Is SMTP supported as a first class transport protocol in ebMS 3.0"?
If not than I can see a problem for two SME's which do not have an
always on HTTP server.
With ebMS 2.0 an SME can always use SMTP to make sure he can go online,
send the ebXML message to the receivers SMTP server and go offline
again. And the receiver can go online, check with its SMTP server for
new ebXML messages, process them and go offline again. Often the SME's
have regular email (maybe from their Internet Service Providers or
someone hosting their website and doing their email) and hence would
also have an "ebXML message" email address.
