use_tls

Since: Version 2026.03.04-bb93ecb1

The functionality described in this section requires version 2026.03.04-bb93ecb1 of KumoMTA, or a more recent version.

If true, the listener will start with TLS enabled and require clients to connect using TLS.

When TLS is enabled, you can optionally specify tls_certificate and tls_private_key. If not specified, a self-signed certificate will be generated automatically.

proxy.start_proxy_listener {
  listen = '0.0.0.0:1080',
  use_tls = true,
}
