[Evolution] Filter based on Specific Header

[Ow Mun Heng <Ow Mun Heng wdc com>]

Hi All,

        I just saw this option in the filter list, called "Specific Header".

I just tried to create a filter that uses the "X-Spam-Flag" and the
start/contains "Yes" but it does not work.

I currently have this  SPAM (marked by spamassassin) which I cannot
filter based on subject as the subject is blank. (but evo shows the SPAM
subject in the New Mail pane but it's blank on the preview pane) and I'm
trying to filter it out.

Here's the head
To: <ow mun heng wdc com>
Subject:
X-Spam-Flag: YES
X-Spam-Status: Yes, score=7.9 required=5.0 tests=BAYES_99,DOMAIN_RATIO,
        MISSING_SUBJECT autolearn=no version=3.0.2-gr0
X-Spam-Report:  *  2.5 DOMAIN_RATIO BODY: Message body mentions many
        internet domains *  4.1 BAYES_99 BODY: Bayesian spam probability
is 99 to
        100% *      [score: 1.0000] *  1.3 MISSING_SUBJECT Missing
Subject: header
X-Spam-Level: *******
X-Spam-Checker-Version: SpamAssassin 3.0.2-gr0 (2004-11-16) on 
        neuromancer.home.net

how does one goes about filtering this?
