It looks like you are using my Debian packages, no? Please read the docs in /usr/share/doc/cyrus21-common/, they explain everything.
I'd guess that your postfix "cyrus" transport is that broken crap using the pipe transport and the deliver/cyrdeliver script that comes in /etc/postfix/master.cf by default? If it is, switch to direct lmtp delivery from postfix to Cyrus. If you still can't get it to work, file a bug in the Debian BTS (use the reportbug package and reportbug command). Make sure to include the full postfix configuration (master.cf and main.cf), because there is where the problem is. -- "One disk to rule them all, One disk to find them.
