Is there a secure connection between Genesys Cloud and AWS SES?

For outgoing emails, Genesys Cloud uses opportunistic TLS that Amazon Web Services (AWS) provides; you cannot set forced TLS. For inbound emails, Genesys Cloud uses TLS to receive emails. This means that Amazon SES always attempts to make a secure connection to the Genesys mail server, and Genesys Cloud accepts a message as secure if it is sent as secure. If Amazon SES cannot establish a secure connection, it sends the message unencrypted.
