100% of the non-English email we're getting is spam, so I added this to
my local.cf file:

ok_languages en

However, I can't see that it's having any effect at all. I'm still
getting tons of Russian and asian spams that don't seem to even be
triggering any SA rules at all. Am I using the config option wrong or is
there some better way to make non-English language emails score higher?
