Have you asked the email's recipient to send the mail tagged a spam back to you ? He need to send the full email as an attached file so that the email comes with all of his header lines. Here is an example of header lines extract from a spam email I received after being processed by SpamAssassin: -- cut here -- X-Spam-Prev-Subject: We cure any desease!
