For some reason, I stopped receiving email notifications where I am mentioned as of Thursday. I have verified that my settings should send an email notification when I am mentioned and also attempted to use the Notification helper, but I am unable to test the notification event of being mentioned. I am still receiving notifications for items where I created the entry or I am a watcher.
ETA: I discovered Mimecast had blocked several Jira emails with the following message: "These incoming messages have been blocked by Mimecast for security reasons. No data has been accepted for them and they can't be retrieved." They were also tagged with "IP found in RBL."
