  • Appreciate that, it’s always helpful to see outside verification. We’re seeing the same thing internally.

  • There’ve been some spammers taking advantage of bugs in Yahoo’s DKIM/FBL handling for a while (and seriously inconveniencing some bystanders in the process). There’s some speculation that this might be an intentional shutdown while they fix those bugs.
    I’ve not heard that anyone has heard anything official from either Yahoo or ReturnPath yet.
