vpopmail and .qmail-default

[Marco Leeflang]

The default behaviour of qmail when no .qmail-default is in the alias
dir the message bounced and the sender received a message.
Is this possible with vpopmail/qmailadmin, i have 2 domains and one i
want to bounce and the other should deliver undeliverd mail to the
postmaster.

greetings,
