Even though their JMRPs are saying you’re not being blocked, that message from Yahoo certainly sounds like you may have an IP that was previously blacklisted. It’s often hard to do bulk mail from a cloud server when the IP has changed hands many times.

I know it’s not a great answer, but you might want to snapshot your server and try to recreate it with a different IP. While they’re an extra cost services like sendgrid and Mandrill are great for this sort of thing.

I have similar problems with Yahoo, AOL and T-Online. You might have an IP address that was formerly assigned to someone who had an open-relay due to mis-configuration or because he actively spammed himself. Unfortunately this can only be resolved by working with the provider’s postmasters. Unfortunately some of them don’t like to play ball with you. I have a very hard time with AOL. sigh.

If they say you are “unblocked”, I guess there is not much you can do. Maybe contact them again and tell them that you still get these messages, even after you got whitelisted and/or comply with all their rules.

Hi, i’ve same problem..
How can check if i’m blacklisted on yahoo?
What’s JMRPs? online checker?

Thanks

Hi guys.

Thanks for your comments.

Okay so basically I persevered for as long as possible to try to build a good IP/sending reputation, but there was no success. I’m definitely inclined to believe due to the poor history of the IP address (or that block of up addresses) I would never be able to reach a decent level of deliverability.

All transactions emails are now being handled by Mandrill and deliverability is excellent. The pricing structure is great (free if you’re only small!). I believe Sendgrid offer a similar service, but from personal experience, Mandrill is fantastic.

blondie63 - JMRP is ‘Junk Mail Reporting Program’. It’s a system whereby when a user marks an email which they receive as spam, JMRP will send you a notification so that message quality can be improved (and you can remove that user from your email list!!)

Cheers,
