I think this event can safely be ignored.
I suppose it could, if that were the only reason this mesage were given, but it's been my experience that this is most often generated because someone sent a missive of some sort to the -request address that SmartList couldn't understand and so punted to me. These mesages usually contain questions for the list owner (subscribers almost never understand the concept of the mailing list server being a machine), and as such _shouldn't_ be "ignored."
If you really want to trash them, you can certainly write a simple procmail filter to send them to /dev/null. But again, remember that if you do, you'll likely be trashing things you _should_ be reading along with those that aren't necessary to be read. Personally, _I_ don't want to miss those messages, even if it means a little occasional inconvenience.
