Due to some problems at the corporate email server, my account (and some others) crossed the bounce threshold in our public Discourse instance.
For two weeks, I had no email notifications from Discourse. And no idea why.
Half of that time I was on vacation. The other half I was visiting our instance very regularly and picking up my notifications the only way I could - directly in the UI.
It seems to me that Discourse should have alerted me - in UI, obvs not by email - that I'd crossed the bounce threshold.
If an active user has an email problem, we should give them a chance to fix it.
Discuss this on our forum.
