Zendesk SMTP Connector rejects agent replies when it is off

When every Zendesk SMTP Connector toggle of an AI Agent is off, Ada now rejects the agent replies that Zendesk sends through the connector. Before, Ada still delivered them. Zendesk shows a send error for each rejected reply.

To turn off the connector, delete the connected address and domain in Zendesk before you turn off the toggles. For the steps, see Disable the connector.
