<you are being warned>
Cross posting inside (postfix + amavisd-new)
</you have been warned>

since we don't know how you did your calculations, we can
hardly say. 
Unless you reject a lotf of mail, I would bet that your
calculations are 
wrong.

Note that it is not that simple to do the maths here:

- if you are not using multiple instances, you need to
correlate before 
and after the filter mail. good luck.
- you should count rejected mail (but not reject_warning)
- when mail is sent to multiple recipients, it is
"sent" once, delivered 
N times
- sames goes in the case of alias expansion
- ...
