I'll object for now. We should NOT pay attention to other X-Spam-
headers (but we should pass them through unless they match the one we
use), because there's potential to let errors in other spam
classification software propagate into bogofilter's judgement. I haven't
set down with pen & paper to look how big the impact would be if we
scored on Spamassassin's headers or something, but it's just a feeling
that it's the wrong thing to do.

And if we deviate from the X-Spam- naming scheme, it makes stripping the
headers (for other tools) more difficult, but if X-Bogosity is the kind
of project identity that's required, then so be it.
