This is the URL for Outlook Web Access. This is not a SMTP-Server Address.
Maybe it is on the same Host, but the OWA Url is absolutely wrong as
RelayHost-Setting in Postfix.

You can try "relayhost = [owa.fic.com.tw]". Maybe it is configured to accept
Mails from Outside/You.

Configure smtp-Auth (http://www.postfix.org/SASL_README.html#client_sasl).

You have the Domain in mydestination, so Postfix believes it is local. If you
want to send Mail to it to the outside, then don't tell Postfix that it is
local.
