That's the point where I missed an important feature of SPF:

If host.example.net has no TXT record, then it doesn't inherit
the sender policy of example.net, but SPF allows to construct
this inheritance with a wildcard "v=spf1 redirect=example.net".

Maybe you could say more about these issues in your text.  Bye.
