I'm perfectly aware of this. To leave the nexthop destination at default
I need a null nexthop. This is against what the documentation says about
sender_dependent_default_transport_maps ("this does not support the
transport_maps syntax for null transport, null nexthop, or null email
addresses.").
What I'm pointing out here is a possible typo in the docs.

If I wanted further advice about yesterday's topic I would have answered
whithout changing the subject, as I did this morning.
But in this case, I don't. I just asked for clarifications about the docs.
And that's exactly the reason I started a new thread.
As far as I'm concerned, our agreement still stands, and I'd
appreciate if you could help with configuration about that matter, since
*those* requirements, as reported yesterday, haven't changed.
