Don't send back spam to spammers: their To: emails are usually wrong,
and you'd get back bounces.
The only good choice should be to stop relaying openly.
As for the present queue, you can program a perl script to open
any file in /var/qmail/queue/ recursively, and deletes any file
containing certain strings. A few lines Perl script, in fact.
Good luck.
