I want to write a custom rule to match if "Any header" contain a

How do I do this ?
Suddenly a lot of garbage is getting thru. Stuff with nonsense text, etc.
This is what I see:
X-Spam-Checker-Version: SpamAssassin 3.3.2 (2011-06-06) on open-122
X-Spam-Level:
X-Spam-Status: No, score=0.1 required=5.0 tests=DECEASED_NO_ML,HTML_MESSAGE

It seems that the hardcore users only resists in a limited amount of
netblocks, so it could make sens
