Note that even though they ask if you are using DomainKey, this does nothing to get you whitelisted, it's only them promoting their sender verification scheme.

I've said this for 4 years now. Sender verification is useless, and it is likely to only cause problems. The vast majority of senders that have either SPF or DomainKey are spammers. Those that fail SPF or DomainKey are often enough forwarded or coming from something like a contact app on a website that inserts the sender. It's not worth the trouble, and you or someone else is much more likely to block legitimate E-mail. Yahoo won't whitelist you if you are using them.

And as a further best practice to what Matt is advising, I'll mention
that ideally you want to send all outbound mail from an IP that is
different from your inbound gateways. And that your outbound bulk mail
would be separate from both.

I did this once about a year and a half ago for a client and they responded fairly quickly, but the full process took about a month before they whitelisted it.

If you are bulk mailing from your hosted mail server, you need to stop. Never send bulk E-mail from a hosted mail server, and it is also good to use a different domain for bulk mailing. I'm not saying that is the case here, but bulk mailing can trip Yahoo.

In the mean time, you might want to see if you can just switch your IP address to see if that will work.

Hi All,

Has anyone figured out how to stop Yahoo from blocking
email?  They've
blocked all email from our servers for about 3 weeks. I've
submitted their
forms but it hasn't done any good.
