My basic advice is "it's best not to mess with it". This is a large,
complex, can of worms, and it's not (in practice) governed by
standards or even written documentation.

If you *must* do it, do a lot of research on what bounce formats
various software recognizes. Relevant software includes mailing list
managers, MUAs (many offer the option to retry or resend a bounce),
and any sort of auto-responder. You will be doing the net a grave
disservice if you break these.

Then, what you need to put your new software in control of nonexistent
addresses is a .qmail-default file in the appropriate place.
