They basically ignore it, and pass it on. If the final destination doesn't
know it, it doesn't do anything. Any nodes in between that get it, will pass a
ping responce back. This was designed to test routes overall basically. Yes,
not every mailer supports it, but the more that do the better. :)
It does technically work the entire route through, each node that does support
PING responds back to the netmail origin, the final destination if it supports
it will reply back to the message with the full complete route path it took.
So you could, if you get it back fully, see the route to AND from the
destination.
