We have the same problem as you.
It's a shame that Zendesk can't handle this, even though it was possible for simple email operations.

I understand that not all errors can be received by the mail sending server.I would like to be able to detect and notify you even if there is an error in the email sending server.
This issue is critical because Zendesk support primarily handles inquiries via email.

Please take immediate action.
