I don't know if it's enough, but it's likely that it's all you'll be able to
solicit here <0.1 wink>.

If you go through your spam folder and look at the clues for messages that
look like the ones that used to be there, do you see these tokens?  It could
be that the spammers sending these types of messages took a holiday this
week <0.5 wink>.  In any case, if you're happy running from source, then
there's nothing stopping you keeping the patch going for your own system -
it seems unlikely that it'll conflict with any tokenizer changes in the near
future.

I suspect that it's that the spams that this helps to nail are already
nailed with other techniques.

I was reading some past messages today and that reminded me to suggest that
you try (if you haven't already) the x-use_bigrams option.  At least some
people have found that it's better at nailing short spams (although maybe
not quite as good at some of the more 'talky' spams).  Testing and developer
experience (I'm not sure if any users have turned the option on) does
indicate that it's a win overall.
