Issue symptoms
My customer uses a no-reply email to contact me but Zendesk suspends all their inbound messages. Can I allow no-reply email addresses to create tickets?
Resolution Steps
Zendesk automatically suspends any emails that come from a noreply@ or no-reply@ email address.
If there is a specific no-reply email address, whose tickets you don't want to suspend, add that email address to your allow list. While this method doesn't guarantee to prevent noreply emails from suspension, it will increase the likelihood that such messages create tickets successfully.
