Since maintenance last week, I no longer receive emails after I start a new question or when somebody has replied to a question.
Looks like something broke.
I got notifications on all of these, including your replies. Did you see anything when I marked the issue as "TI Thinks Resolved" earlier? That's a different path and was unaffected, so you should have seen those even if notifications were not working.
Many, many apologies, it was us all along!
Unless something changed about the nature of the emails since maintenance then coincidentally our spam filters started blocking them last week. The best bit is that I don't even get to know if I have any blocked emails. I had to speculatively ask the IT department who confirmed this was the case then released an avalanche of E2E emails.
I asked further about the root cause and our IT department has discovered an issue described as follows:
"The emails are being blocked because they are failing a mandatory SPF/DMARC check. This isn't something that we can resolve, it is a configuration issue on the senders infrastructure."
Please can I have contact details for an IT representative on your side that can talk to my IT manager about this issue?
I have changed the title of the thread to reflect the issue.
