The problem here is the '|'. It is an operator which says match either
the pattern to the left or the pattern to the right. In your case, the
pattern to the right is the null pattern which matches everywhere so
that pattern will always match.

I don't know how you tested, but the patterns in header_filter_rules are
matched only against message and sub-part headers, not against any body

To match against body text, you need a custom handler. See
<https://wiki.list.org/x/4030615> and the example MyHandler.py script
linked therefrom.
