Thanks for the example, makes it so much clearer. For that use case, you should do an SPF-include of Yahoo's SPF inside your own SPF record. Yes, provided Yahoo had any SPF at all (which they did not until very recently), and also provided the included-SPF already involved less that 10 DNS-queries. If those conditions were false, I would take it as an implied declaration from ymail that your use case is not welcome with them, so why force the issue with them?
