Hi everyone! I’m writing from the help desk of an ISP in Michigan and we’ve been blocked by Yahoo for more than 2 weeks now. I’ve seen those exact same messages above quite a few times lately! I was starting to get very mad at Samuel until I realized it was an auto-responder

I have a case number of: 46796660

Ryan, any chance you think you can send a message to your contact on my behalf? It’s driving us nuts having to hear all these people whine about not being able to send to friends and family at Yahoo. We’ve tried changing IP addresses and they seem to have our entire class c blocked.

Hi Ryan, I’ll do so. I also mentioned it to Chris during Highland Fling. I’ll shoot both of you an email ASAP.

Everyone else: Thanks for your support and tips. I’m going to see if we can’t change the IP.

I had this problem with a client’s server last month. It took them 5 weeks to clear the block and whitelist them. We only had problems when doing large mailings (300,000+). no problem with small (<10,000) mailings.

Aral, shoot me email offline and I’ll try to get you in touch with someone in the antispam team here at Yahoo!.

It’s possible that your IP address is blacklisted with Yahoo! (and maybe others) due to behaviour by the previous owners of that address. Maybe your ISP can assign you a new/additional IP to use with your server.

Yahoo does have this problem and you’re not the first one to see it. I also have to send out mailers and even though I send them once in a month or so, everytime my mail queue gets choked. And no matter what data you send them, there’s no relief coming your way.

What I do is (and what you can do is), to let the mail queue retry the message sending over and over again. I’ve read that this is the only way because there’s no more explanation from Yahoo over this except the error message you already have seen. And the mail queue does get cleared gradually on its own.
