Yahoo delays, part 3: Yahoo speaks

Yahoo is aware of the recent problems and have been working feverishly to fix them. A Yahoo employee posted to a mailing list earlier today, explaining some of the recent issues. The summary is:
1) The Yahoo delays are a result of a tighter spam filtering policy. The delays are the result of the system erroneously recognizing email as spam and deferring delivery. They do believe that retrying long enough will result in all mail being delivered to Yahoo recipients.
2) They have been continually making fixes to the system over the last few days and senders should see queues start to empty over the next few hours.
3) They believe the adjustments made will resolve the deferral problems. If you continue to see problems, you can contact them through the form at http://postmaster.yahoo.com/.
4) They are working to provide more self-serve information at http://postmaster.yahoo.com/ as well as timely service updates.

Update on Yahoo and the PBL

Last week I requested details about Yahoo rejections for IPs pointing to the PBL when the IP was not on the PBL. A blog reader did provide me with extremely useful logs documenting the problem. Thank you!
Based on my examination of the logs, this appears to be a problem only on some of the Yahoo! MXs. In fact, in the logs I was sent, the email was rejected from 2 machines and then eventually accepted by a third.
I have forwarded those logs onto Yahoo who are looking into the issue. I have also talked with one of the Spamhaus volunteers and Spamhaus is aware of the issue as well.
The right people are looking at the issue and Spamhaus and Yahoo are both working on fixing this.
Thanks for the reports and for the logs.
