Silveracre Comics review: yahoo bouncing customer receipt emails

Yahoo is preventing our business from sending client order confirmations. We do not send spam or have any issues with hacked server etc, hosted by olm.net. Can you please reset the block so that we can continue to communicate with customers who have yahoo emails that have placed orders with us. This is causing a serious problem for us which is the largest European rare comic business.

Or pass on this complaint to the respective support department that can reset the block.

here is an example of the problem. yahoo.com ymail.com sky . com or . co.uk

I have plenty more with the same issue.

You can also reply to the web engineer who has the task to sort this problem out with Yahoo. Thanks
