How to customize bounced back messages

[Yu Wang]

Hi there,

Suppose Qmail cannot send an email for a user, so it will send back a
message to the user telling her (or him) that that message cannot be
delivered. How can I customize the returned message so that a
non-English speaking user can know what has happened clearly.

BTW, is there any effort to provide localized Qmail package for
non-English speaking users? I mean, if there are some such efforts,
Qmail will be expected to have more widespread use.


Thank you,
w.y.
