Yahoo update

It has been quite a while since I have had the opportunity to share information about Yahoo here on the blog, but there is new information to share.
Yesterday, Mark Risher from Yahoo spent some time talking with people about all things spam over at Yahoo. Matt from EmailKarma posted the transcripts as well as some excerpts from the talk. The really interesting bit, for me, was confirmation that Yahoo will be bringing back their FBL in the next few weeks. I have been hearing rumors about the return of the FBL for a while now, and it seems the general timeline (fall-ish) is accurate.
Speaking of the feedback loop, there have also been rumors that Yahoo is not accepting any changes to existing feedback loops. This does not seem to be the case. According to an internal person, companies who are currently in the beta FBL program can make changes to the program by contacting the postmaster team.

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.

Articles I read today

It has been a rather busy day today, I do not have a full blog post. I did see a couple posts come across my RSS feeds. Both of them have content I want to talk about and discuss in a little more detail, as I think they touched on some very interesting issues.
Network World has an article interviewing Mark Risher from Yahoo. The article discusses Yahoo’s use of DomainKeys as part of their inbound mail filtering.
Mickey has an article about how to deal with ISPs when attempting to troubleshoot a blocking issue.
More details and commentary on both articles later this week.

Yahoo delays, part 2

A number of people have posted to various mailing lists and made blog posts pointing to the Yahoo Mail blog post discussing recent problems Yahoo was having with mail. The general feeling seemed to be “AHA! That’s what is wrong!”
Unlike many of my peers, I do not think this explains the delivery problems senders have been seeing while attempting to deliver mail to Yahoo. The Yahoo mail blog article is talking about the Yahoo outgoing mailservers (smarthosts) for their non-webmail users. It is extremely unlikely that these are the same servers used for incoming email.
While I sympathize with everyone who had the AHA! moment and thought their delivery problems were being acknowledged and addressed by Yahoo! I do not think this is really what that blog post is saying.
I am hearing from people that Yahoo is aware of a problem with delayed incoming email, and they are working on fixing it. This does seem to be a broader problem than just bulk mailers, I am hearing from small and mid-size ISPs that they are having significant problems delivering email to Yahoo, too.
