[Mailman-Users] Bouncing Mail - How is it treated?

[Angel Gabriel]

I'd like to know how bouncing mail is treated, is it removed from the list?
Will I be notified of each bouncing address?? How long before it's taken off
the list? What about people who use web mail, can mailman tell the
difference between an error because of a full mailbox, and an error because
of a non existent user?
