OK, first mail passes through SA. I have it configured to only add info
in the X- headers.
Then the mail passes through dspam. dspam uses the info in SA's X headers
as tokens in its decision. So your email has the following headers:

Now let's look at a piece of junk:
X-Spam-Flag: YES
X-Spam-Checker-Version: SpamAssassin 3.2.5 (2008-06-10) on selene.seiner.lan
X-Spam-Level: ***********

you can see that almost all the tokens dspam used came from the X-Spam
headers.
