Again, could you please do what I have asked here? It might be very 
interesting to look at.

Another thing you could try is to use `rspamadm mime stat -b` command 
for a sample. Then, you will see the tokens Rspamd uses for that 
particular email. Afterwards, you can even check them in Redis using 
something like `HGETALL RS_<number>`, where `number` is printed by `mime 
stat`. You also will see this information if you do like I've asked in 
my previous email quoted above.
