Are there any JMS implementations that utilize email under the covers for interclient communication?
Mario Prados I'm not 100% sure, but I could say that probably nobody will be implementing JMS using e-mail as the underlying transport. If you take a look at Sun's JMS web page, you'll see the list of JMS implementors. All of them are MOMs (IBM, Fiorano, TIBCO, Allaire, etc.); thus, you can expect all of them will put JMS interfaces on top of their respective products.
