[Mailman-Developers] Re: Reason for file in mailman/src/mailman/model?

A follow up question I do not get what "bounces.py" in "mailman/src/mailman" is trying to achieve?

From what I understand we have a func to send the bounce back (this happens in MTA so nothing unusual) Since Verp does not work effectively with every MTA so we parse the Verp message and send the Verp probes(send_probe func).

I have referred to "https://wiki.list.org/DOC/So%20what%20is%20this%20VERP%20stuff" so this has helped me in probe stuff.

Q1--Is this right or some pointers I am missing?

Q2--What exactly is the meaning of ProbeVerp class and _ProbePendable class?
