Hmmm. Isn't that a violation of some RFC? Because allowing a domain to send but never receive means that there is no recourse for abuse@ postmaster@ etc. Indeed, not even anywhere to send DSN's...

Perhaps I am missing something, please set me straight.  :)

Yahoo is saying that means the domain does not send email - basicly its
similar to when you put "v=spf1 -all" in your spf record and they want
people to use it as such replacement (yahoo is not a fan or others doing
spf as you know...). However it really is a pure replacement since with SPF you're still leaving yourself option to receive email to that domain (and just indicate it is not used in return-path).
