Spam email gets through with X-Spam-Score header present but no score.

[GQsm <na...@blazinhot.com>]

Sorry if this is old hat. I've googled a lot, searched the archived mailing
list and read a lot of FAQs but have found nothing on this problem.
 
I have had a few spam emails recently that got straight through to my inbox.
 
On inspection the header shows
"X-Spam-Status: No, score= "
"X-Spam-Score: "
and
"X-Spam-Bar: "
 
I thought that every email that went through SA would receive a real number
score whether spam or not and under no instance should the score be
non-exsistent.
 
Below is most of the header from the latest email of this kind.
Has anyone any ideas what's going on and how I fix it?

It depends how you have things setup, but if the mail gets to SA, then it
would generally have a score and such, yes.

How big was this mail, and how do you call SA?  There's no
X-Spam-Checker-Version header.

My guess is either a problem with a third-party tool (milter, etc,)
or the message had those headers and it's > the max message size and
you use spamc.
