Hello,
I've reviewed all of the settings in the "Configuring Mail" section and did send a test email to my account and I was able to receive the test email that I sent. Our instance used to work effectively every day with thousands of users receiving emails, all issue triggers, etc.
Unfortunately, I was clueless at this situation when the test email was working and "Notification Helper" is not showing an error.
Thanks,
