Email Security.cloud

Good evening. We are running into a scenario where 2 separate clients at 2 separate companies and therefore 2 different domains are no longer receiving email messages from a specific email address from our company. Our company utilizes Outlook 365 and each of the organizations experiencing challenges receiving our email messages are utilizing Messagelabs. We are able to trace our outgoing messages and verify delivery to "cluster4.us.messagelabs.com at 216.82.242.179" Each recipient organization states they ceased receiving incoming messages from us within the same time period (around 7/28/2016). We are not receiving any error messages not are we receiving an NDR. Additional information can be provided upon request. Any assistance is greatly appreciated. Thanks in advance -dF

Hi,

Is this issue still ongoing. Ever so sorry for the late reply. If the issue is still ongoing then I would need to know more details in order to investigate. I would need senders email address as well as the sending IP and also the recipients email address. Also the details of these should of been sent within the last 14 days as we only keep full logs for that time period.

Kind regards

Kevin Brosnan
