Hi d09h,
We have the same issue. We just went from a standalone NCM server to an integrated NCM/NPM solution with multiple polling engines pointing to the main Orion Web Server and we are also receiving separate email's from each server with change configs. That's fine, but the problem with its current implementation is that the "from" address in the email's are exactly the same for each poller, so we have no idea which email is from which poller and there does not seem to be a way to customize that. Ideally it would be nice to have that merged into a single email, or at the very least be able to customize the "from" address for each poller.
