Maintenance & Send Email Alerts

Hi Xibo’s staffs,
I have Xibo CMS installed on Ubuntu. I have setup the Email Alerts as mentioned in this post:

Here are some screenshots about configuration:

I think I had done throughout the tut, however, it did not work. I didnot receive any email alerts.
Is there anything missing? what should I do more to make it work?
Thanks in advance.

Is this 1.8.2 CMS? If it is, is it docker or manual/custom installation?

If it’s 1.8.2 custom/manual installation is the XTR configured?

How long was the display offline and then back online after you’ve made those configuration changes?
Also what’s the collection interval for your player?
