I am using my ISY99i v3.2.6 with SmartHome Insteon. Love it! My ISY99i is fully established on the internet and I am able to use it from my smartphone. About 1 week ago I set up notifications and they worked until yesterday. When I set up Emails/Notifications, Settings/Groups, I checked the box in SMTP Settings to "Use Default." Worked fine but now quit sending. Also the "Test" feature no longer works. Tried establishing a new group also but still not working. Any thoughts what I am doing wrong or not doing? What changed? Could it be because I'm using the "Use Default" setting? Thanks!
