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

Perhaps a use case for an ebXML intermediary. Have some address that your partners can always HTTP push ebMS 3.0 messages to, even when you're not online.  Then you can ebMS3 HTTP Pull messages from that intermediary. 

 

Sacha's hint is that the SMTP/POP3 combination has offered this model for email for many years, so that using SMTP/POP3 as message transport would allow any ISP to become an ebMS3 intermediary ..

Sacha,

 

Nothing to stop you using ebMS v2.0 SMTP support then here - for generic use.

 

In your model the little guys will all be v2.0 clients and the SMTP server takes the place of the ebMS v3 server.

 

Now - if you have a big partner with an ebMS v3 server - then no need for those messy gmail accounts!

 

In fact the ideal would be to have the ebMS client "call home" on say a 2 or 3 times daily schedule - same way as you can check email too.

 

I think a more realistic model is one where people are involved in a marketplace with partners - and they are therefore going to have available a central ebMS server. 

 

However - for those that don't then the central SMTP server provides that equivalent work - and the big partner can interchange those emails from their ebMS server.

also sending if you want to send but the receiver is down.

I understand but if I want to send a message to you and so my server
puts it into its queue for you, so that you can pull and then my server
sends it to you. BUT I do not want to have my server up and running
until you please to come and "pull" for the message ... I may have a
very limited time (short window) that I can be online.

so I think the pull mode is no big help if both parties are small and
not online all the time. I think the pull mode is excellent when there
is a big party which has an always on http server and lots of small
parties that come and go online.

But for two small parties that come and go online the SMTP protocol is
nice. Also because SMTP services are available everywhere (eg simply
open up a gmail account)

I would say that there is no pull mode required for SMTP transport
protocol as Dale said the POP is the equivalent for the PULL.

Well you would need such a provider ... and its right now unlikely that
if you a are a small organisation that your ISP, or web-page provider
will provide such an "ebXML" service.
