Validate recipients at your MTA. Tell us which MTA you're using and we can
probably help you configure it.

Venturing a guess from your mail headers, you seem to be using sendmail, and
that feeds into some kind of Microsoft "server".

Look into using milter-ahead on your sendmail box. This will cause sendmail to
validate the destination address with your Microsoft box before accepting the
message.
