Are you sure? If you haven't changed VERP_PROBE_FORMAT in mm_cfg.py,
this should be

mylist-bounces+client=clientdomain at lists.mydomain.com

If you have changed the '+' to '-' in VERP_PROBE_FORMAT in mm_cfg.py,
you should remove that change, and fix whatever problem caused you to
change it in qmail and not in Mailman.

Did you do the fix_url part for existing lists?

It's working with normal bounces, but not with the VERP like probe

This is the same as the first issue above and it is a qmail issue. Did
you see my reply to your post of Oct 10 which is at

I am not including you as an addressee of this reply as I normally
would in the hope that you are receiving from the list at least. If
you did see the above reply, what didn't you understand?
