I have no supporting log to check whether the emails are actually sent
to you. All I have is the list of emails that were sent, and these
emails do have the TO: field to you.

Here are the recent emails sent to you:

Yes we need to fix it. The same lost email issue has happened for
someone else, which was fixed by changing the email address. I can
conveniently redirect reports to any other email addresses you have.
