This means your provider wants you to authenticate using SMTP auth.
You need a login and password (perhaps identical to your indial data).

[ http://www.exim.org/exim-html-3.30/doc/html/spec_19.html#SEC554 ]

  authenticate_hosts (smtp)

  Type: host list
  Default: unset
  
  This option is available only when Exim is built to contain support for
  at least one of the SMTP authentication mechanisms. It provides a list
  of servers to which, provided they announce authentication support, Exim
  will attempt to authenticate as a client when it connects. See chapter
  35 for details.

You can not send TLS Mail there because the remote side is misconfigured. 
It announces STARTTLS but then it fails.
Please talk to tunbridge.com.sg about fixing this.
