Yahoo FBL Down
We’re seeing multiple reports that the Yahoo feedback loop stopped working some time in the past couple of days. If you’re not seeing reports, it’s not just you.

I’m seeing scattered reports today that a lot of places are seeing backed up queues to Yahoo. They’ve had some problems over the last few days and seem to be still recovering. It’s looking like it’s something internal to Yahoo. One set of error messages I’ve seen reported by numerous people is: “451
4.3.2 Internal error reading data.”
It’s not you, and it’s not spam related. But it is putting a crimp in a lot of companies attempts to send lots of email ahead of black friday and cyber monday.
A couple weeks ago, I published a blog post about monetizing the complaint stream. The premise was that ESPs could offer lower base rates for sending if the customer agreed to pay per complaint. The idea came to me while talking with a deliverability expert at a major ESP. One of their potential customer wanted the ESP to allow them to mail purchased lists. The customer even offered to indemnify the ESP and assume all legal risk for mailing purchased lists.
While on the surface this may seem like a generous offer, there aren’t many legal liabilities associated with sending email. Follow a few basic rules that most of us learn in Kindergarten (say your name, stop poking when asked, don’t lie) and there’s no chance you’ll be legally liable for your actions.
Legal liability is not really the concern for most ESPs. The bigger issues for ESPs including overall sending reputation and cost associated with resolving a block. The idea behind monetizing the complaint stream was making the customer bear some of the risk for bad sends. ESP customers do a lot of bad things, up to and including spamming, without having any financial consequences for the behavior. By sharing in the non-legal consequences of spamming, the customer may feel some of the effect of their bad decisions.
Right now, ESPs really protect customers from consequences. The ESP pays for the compliance team. The ESP handles negotiations with ISPs and filtering companies. The cost of this is partially built into the sending pricing, but if there is a big problem, the ESP ends up shouldering the bulk of the resolution costs. In some cases, the ESP even loses revenue as they disconnect the sender.
ESPs hide the cost of bad decisions from customers and do not incentivize customers to make good decisions. Maybe if they started making customers shoulder some of the financial liability for spamming there’d be less spamming.
Via mailing lists and Al Iverson’s Spamresource blog, Yahoo China domains (yahoo.com.cn and yahoo.cn) are no longer accepting email. Yahoo announced in April of 2013 they are shutting down their email services in August of the same year and advises users to create new accounts with Alibana. While the domains still have valid MX records, they are no longer accepting mail. There is no direct mapping from Yahoo China addresses to Alimail (Alibana’s email service).
When attempting to send emails to these two domains, the reject will be a “550 relaying denied” message. Now would be a good time to update your lists and remove any yahoo.com.cn and yahoo.cn addresses.
