SpamAssassin coming back with zero scores

spamassassin

When I run tests (spamassassin -t) on obvious spam, I get results like this:

Content analysis details:   (2.0 points, 5.0 required)

 pts rule name              description
---- ---------------------- --------------------------------------------------
-0.0 NO_RELAYS              Informational: message was not relayed via SMTP
 0.0 T_TVD_MIME_NO_HEADERS  BODY: T_TVD_MIME_NO_HEADERS
 0.0 HTML_MESSAGE           BODY: HTML included in message
 2.0 PYZOR_CHECK            Listed in Pyzor (http://pyzor.sf.net/)
-0.0 NO_RECEIVED            Informational: message has no Received headers
 0.0 T_REMOTE_IMAGE         Message contains an external image

It's clearly finding things wrong with it, but everything scores at 0 points for some reason (except Pyzor). Have I configured something wrong?

The comment Informational: message was not relayed via SMTP implies that the message your scanning has little or no useful header information. Did you by any chance save or export the e-mail message, rather than working on the raw message in your Mailstore?

On testing with some of my higher scoring Spam after removing the Received: headers I get the same informational message and it typically results in a 10 point drop in the score SpamAssassin assigns...
