I have been trying to tune scores to achieve better matches with spam that
is getting through. And one test which shows up is HTML_FONT_LOW_CONTRAST
which is being scored for 0. Doing a scan of my incoming mail flow this is
a huge signal, perhaps even a disqualifying one as I have yet to find a
legitimate piece of email where this is true and it isn't spam.
So in my local.cf file I added:
score HTML_FONT_LOW_CONTRAST 10
To have it add 10 points to the spam score, recompiled rules and restarted
spamd. Yet it still gives it 0 points.
0.0 HTML_FONT_LOW_CONTRAST BODY: HTML font color similar or identical to
background
How do I change this value?
In your local config file:
score HTML_FONT_LOW_CONTRAST 1.000 # or whatever score you prefer
The reason it scores so low in the base ruleset is the S/O is *very* low
in the masscheck corpora - 0.114 - 4% spam hits vs. 31% ham hits.
You might want to be careful if you intend to treat that as a poison pill
by itself...
I'll take a look at whether its performance can be improved.
