I think I saw a qmail patch that let you use a badrcptto or badmailto file in /var/qmail/controls. Check http://www.qmail.org and search for badrcptto (there are two of them right together). If this works, it would reject the mail at the smtp level.
If you're dead set on using vpopmail functionality to bounce the message, then you should be able to use the /home/vpopmail/domains/<your domain>/.qmail-default file to bounce it. I think rejecting at the smtp level would be the most efficient since you wouldn't have to accept the whole message then. Good luck.
