A number of people are reporting seeing a new bounce from Yahoo. “smtp;553 Mail from x.x.x.x not allowed – [10]”. My clients have been asking and other people have been asking about this. It seems that something is changing at Y! More information as I hear it.
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.
Loose ends from my previous Yahoo posts:
Yahoo posted some suggestions about contacting their postmaster group over on the ymail blog. They also explained what they were doing to solve the problems with response delays.
Some of the problem is being caused by excessive follow-up emails, either because senders did not provide all the necessary information initially or because they are asking why they have not heard anything. Each of these requires more work on the part of Yahoo and throws the queues into further disarray and puts everyone even more behind.
Yahoo asks that people be patient, they are working through things. On their end, they have added more staff to the postmaster team. They also suggest senders can help by providing ALL the information they ask for at http://postmaster.yahoo.com/ before submitting the request. Incomplete requests contribute even more to the backlog as Yahoo employees have to chase down senders to get their full information.
People are reporting delivery delays into Yahoo over the last day or so. Yahoo is having some general connectivity problems and are working to correct the issue.
