By default, qmail sends double bounces to postmaster, not
MAILER-DAEMON. Bounces and double bounces are sent *from*
MAILER-DAEMON, but removing a MAILER-DAEMON alias won't stop them from
being sent r delivered to postmaster.

What does "the message DID" mean?
>My question is : Where this messages to an unknown user is stored ?
They're not stored, they're returned to the sender (a bounce). If the
sender is invalid, the bounce bounces (a double bounce), which is sent
to postmaster on recipient's system.

qmail doesn't discard messages, bounces, or double bounces, but triple
bounces (double bounces that can't be delivered to postmaster (or
doublebounceto)) *are* discarded.
