Hi Jens, The Dead Letter Channel makes much sense to me :) but I think the notification through IM and all the rest has to e done through the configuration by the admin.
It is nice to support all these through a console but at least for the moment we don't have a console inside Synapse, may be you are talking about the WSO2 ESB console for synapse, in which case yes of course we can do that. You could go ahead and add a JIRA for the Dead Letter Channel implementation. I think we can implement this as a mediator.
