Thank you for your feedback.
Today you can see messages which are “pending” in a queue through Message Trace feature. In the Mail flow Dashboard, you can see messages queued for more than an hour. We’ve also created alerting for this condition. Can you tell us what other things you need and what the scenarios look like / how commonly you need to perform the task?
This would help us when evaluating this item further.Randy in Marin commented
I have 90000 emails incoming from a faulty server. Can my admin delete these? Do I have to actually receive all 90000 emails.
