Stoped getting Emails from Firewall

Hi

A few weeks ago I stopped receiving emails from one on my firewalls. I checked all of the settings that I can find and see no problem. I was looking for logs that might shed light, but the system does not keep an email log that I could find.

I checked to make sure the following is correct.

1)Management-> System Settings->Organizational->Administrator's Email Address
2)Management->Notifications->Global and Notifications
3)Logging & Reporting->Executive Report->Executive Report->Configuration

Anything I'm missing? I still get alerts from another firewall so the email works.

I can ping google.com so DNS works
