As a first hint, I think you must search at qmail's configuration because
Cyrus cannot produce a bounce, can it?
Cyrus only understands LMTP and IMAP and both of them do not generate bounces
(Sieve Scripts are a different story, because they are using
/usr/lib/sendmail when forwarding mail).
It would be nice if you could tell us your configuration (how did you
couple QMAIL with Cyrus? via /var/users/assign?) and then we can look if we
can help you (sorry for the "we" as I am very new to this mailing list but
very "old" when it goes to Cyrus IMAPD things, I am using this beast from Ver-
sions 1.5 on and now we have 2.0.16 working like a charm).
