listen

Specifies the local IP and port number to which the ESMTP service should bind and listen.

Use 0.0.0.0 to bind to all IPv4 addresses.

kumo.start_esmtp_listener {
  listen = '0.0.0.0:25',
}

Note

This option cannot be used in dynamic listener contexts such as within via, peer or within the parameters returned from smtp_server_get_dynamic_parameters. It can only be used directly at the top level within the kumo.start_esmtp_listener call.
