and the other stanza it sends.
It should be something like a shim header to be added to a message. Each
relay on the way would have to check if the next relay supports this
shim header. If it doesn't it will bounce the stanza back (without it's
content as the way back might have other characteristics as well). If
the next relay supports it, it will forward it if the link to this next
relay is protected, if not same as if the next hop does not support the
