Write your own qmail-queue "replacement" that filters for sender and
drops mails from "the notorious". All other mail is than passed to
qmail-queue as usual.
This way you don't have to fiddle with qmail sources, you only have to
have a QMAILQUEUE-patched qmail.
If this sender is worth the work ... additionally other might benefit
from your work, maybe there are other people that like to really
blackhole some senders instead of simply rejecting their messages.
