Yahoo sent out an email yesterday evening to their postmaster mailing list saying they believe they have fixed the issue that I mentioned earlier this week. Some of the MXs were erroneously rejecting mail claiming that the sending IPs were on the XBL.
Someone twittered me a question about Y! and their ARF reports. Apparently the ARF header is not including AM/PM which is causing problems for some people. Yahoo is aware of the issue and looking into it.
On a housekeeping note, sorry for the lack of postings this week. I’m still recoving from the trip and while I have a lot of things I want to talk about (including responding to the great comments on transactional email) I am swamped with catching up.
Al writes about a Yahoo delivery problem where they have identified a particular Yahoo MX that is falsely returning “mail blocked due to XBL.” The IPs in question are not on the XBL. Yahoo is aware of the issue and are working on a resolution. If you are seeing these bounces, Yahoo is aware of the issue. Exacttarget has worked around the issue by suspending deliveries to the affected MX.
