W-29 email delivery problems – 3 and 4 May

We are aware with a problem with email delivery to service providers that use the CloudMark CSI IP Reputation tool. One or more of the server’s IP addresses is currently blacklisted.

We are not aware of a spam problem on our side and are in contact with CloudMark to resolve the problem.

We have no isolated the cause of the problem to be a compromised account password on our server. We have plugged that hole, and are working with CloudMark to remove the blacklisting. Please bear with us while this process takes its course.

Update 5 May 14:00 UTC:
CloudMark has removed the blacklisting. Please allow a couple of hours for this to propagate to email providers that rely on this service.
