The site associated with this mailserver seems perfectly legitimate:
Quote:
Yew Wah international education service is built upon the many decades of experience of Yew Chung Education Foundation in offering quality international education in Hong Kong and Mainland China

http://www.yewwah.com/index-e.htm

So it seems plausible to assume their mailswerver has been compromised and added some extended functionality... There are some indicators in support of this theory:

Though recent IIS versions have finally become more secure, this alone is not sufficient if the server is misconfigured and/or hasn't got the latest patches applied. The mail banner does not look like a Postfix, Exim or Sendmail installation:

Perhaps exchange in stealth mode or some other proprietary, windows based mail solution.
