Unable to send email on yahoo domain from exchange 2010

We are using Microsoft Exchange 2010. Emails which we sent on yahoo domain is stuck on our hub transport machine when I see Queue Viewer on it. ON Queue Viewer Delivery type is DnsConnectorDelivery and Status showing Retry. We are facing this issue only with yahoo. Please do needful to resolve the issue.

1) Do you have any HUB/Edge server sending mail outside? Or
2) Is there any Anti Spam gateway for sending mail like Iron port?

This looks DNS related issue with your public facing server/gateway.
Probably getting touch with ISP may help.

1) check your domain status either it's blacklisted in any of ..

www.mxtoolbox.com

if it's blacklisted in any.. .then remove it from block list

2) or it could be reverse DNS issue you'll get the result in www.mxtoolbox.com...
resolve it...

all the best

Mails would be rejected by recipient domain when IP's are blacklisted, instead of piling up in HUB queues

Our IP's are not blacklisted and there are no reverse dns issues. Secondly our Hub is directly send emails on internet.

I had a similar issue recently and it was because there were 1,000s of spam emails running through my Hub Transport and they would not deliver.

Have you checked that the messages queuing are valid?
