To encrypt SMTP with TLS on a Cisco Secure Email Gateway appliance when the sender requires TLS verification, the components that are required are an X.509 certificate and matching private key from a CA. The certificate must be signed by a trusted CA and contain the domain name or IP address of the listener in the Subject or Subject Alternative Name fields. The private key must be unencrypted and match the certificate. References: [Cisco Secure Email Gateway Administrator Guide - Configuring TLS]

To enable File Reputation and File Analysis on the Cisco Secure Email Gateway appliance, the administrator must configure the appliance to use SSL for the connection to the File Reputation server. This will ensure that the communication between the appliance and the cloud service is secure and encrypted. The administrator must also upload a valid certificate from a trusted CA on the appliance for this purpose. The other options are not required or effective for this task. References: [Cisco Secure Email Gateway Administrator Guide - Configuring File Reputation and File Analysis]
