Scoring questions

Interestingly, I have been getting a boatload of these this morning.
They are getting flagged as *****SPAM*****, but the headers show:

X-Spam-Flag: NO X-Spam-Score: 0 X-Spam-Level: X-Spam-Status: No, score=0 
tagged_above=-9999 required=5 tests=[HTML_MESSAGE=0.001, 
NO_RELAYS=-0.001] autolearn=ham autolearn_force=no


In the content, it shows being caught by spamassassin with:

Content analysis details:   (25.7 points, 4.0 required)

  pts rule name              description
---- ---------------------- --------------------------------------------------
  1.2 MIME_HTML_ONLY         BODY: Message only has text/html MIME parts
  0.0 HTML_MESSAGE           BODY: HTML included in message
  2.0 BAYES_50               BODY: Bayes spam probability is 40 to 60%
                             [score: 0.4823]
  1.7 RDNS_DYNAMIC           Delivered to internal network by host with
                             dynamic-looking rDNS
  0.0 HTML_MIME_NO_HTML_TAG  HTML-only message, but there is no HTML tag
  5.0 KB_WAM_LONELY_WOMEN    Lonely Women Scam of the Day
  2.9 HELO_DYNAMIC_HCC       Relay HELO'd using suspicious hostname (HCC)
  2.5 PHP_ORIG_SCRIPT        Sent by bot & other signs
  3.7 HELO_DYNAMIC_IPADDR    Relay HELO'd using suspicious hostname (IP addr
                             1)
  1.5 HELO_DYNAMIC_DHCP      Relay HELO'd using suspicious hostname (DHCP)
  1.0 BODY_URI_ONLY          Message body is only a URI in one line of text or for
                             an image
  1.8 TO_NO_BRKTS_HTML_ONLY  To: lacks brackets and HTML only
  2.4 TO_NO_BRKTS_DYNIP      To: lacks brackets and dynamic rDNS

Which is what I would expect.
Could you enlighten me on where exactly the X-Spam- headers are coming 
from ?
