Can messages be sent successfully through this send connector?
Which smart host authentication do you configure for your send connector?
If you choose the basic authentication, and select "Offer basic authentication only after starting TLS", a certificate on the smart host is needed and it contains the FQDN of the smart host that's defined on the Send connector. You can unselect "Offer basic authentication only after starting TLS" to see if the issue persists.
For your reference: Use the EAC to create a Send connector that uses smart host routing.
