Unable to send email alert from rancher?

Hello All,

I have deployed rancher on azure server and i have kubernetes cluster. I want to send the email alerts when a pod goes down. I have added alert for that and also a email notifier.
Email notifier works fine and able to send test email.

But when pod goes down the alert status turned to Alerting but i did not receive any email from rancher. I have raised issue on github as well.

Kindly let me know what else i need to do for receiving alert email.
