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.
