Question undelivered message notification

[Ravenworks]

Hi

Need some help. I had this server but I deleted a long time ago off my plesk. I now use a different server name. On a recent update I started receiving this message. It is a notification of updates needed on a wordpress site I have. How can I remove the server name from this notification setup as obviously I don't use it. I have a self managed account so giving help for this is not my hosts top priority so if anyone can help me it would be fantastic.
