[Mailman-Developers] Cannnot find the processing of bounces as `hard` and `soft`

Somewhat details regarding this can be found in this thread also.

Currently, in the mailman/src/mailman/runners/bounce.py I do not see whether the separation of bounces as hard and soft is implemented. According to the previous version of Mailman, the bounce_score is increased accordingly ( see the Bounce processing section of this page ) depending upon the type of bounce. I intend to follow that implementation. If not required I can drop that implementation and just increase the bounce_score as an integer always.

Pointers on this issue are appreciated. Am I missing something here?
