The Enforced TLS settings specify whether or not the recipient is required to support TLS or have a valid certificate. The Enforced TLS endpoint supports retrieving and updating TLS settings.
If either require_tls or require_valid_cert is set to true, the recipient must support TLS 1.1 or higher or have a valid certificate. If these conditions are not met, we drop the message and send a block event with "TLS required but not supported" as the description.
