Well, our good friends at Yahoo are at it again.
Once again they are deferring mail for no apparent reason.
Nothing has changed on my system and yet they haven’t accepted a message to deliver to one of their users in 3 days (maybe more). And, of course, there’s no way to actually contact a human to find out what is going wrong.
I’m on Yahoo’s email feedback loop … so I’m notified when someone complains about a message. Nothing has come in recently from the feedback loop.
I used to be on their bulk sender white-list. There was never a mention of having to renew the white-list approval.
A note to all my friends … DO NOT USE YAHOO FOR EMAIL! Especially for business email. The folks at Yahoo do NOT know how to provide service.
Oh, and FWIW, yahoo customer service tends to ignore questions that are too complex for their script reading drones to answer.
