Unable to receive bounce message

[Yiqian Zhang]

I have sent a couple of emails to a client without knowing that his email
address has been changed. Yet I have not received any bounce messages. Is
this a configuration issue with my company's mail server or the receipt's? Is
it standard for a company's mail server to be set up to send bounce
immediately?

Most likely at the recipient's end. Maybe the address still exists on their
server. Perhaps as an alias to the new address so they receive email for
both addresses, or even kept available for the email administrator to check
for important emails to the old address.

And it is certainly possible that the recipient's email admin has blocked
non-delivery reports (NDRs).
