Cyrus IMAP and Sieve

[Bob Chiodini <rchiodin@xxxxxxxxxxxxx>]

I'm trying to setup sieve to filter my email without any luck.  I'm
running the Cyrus IMAP server, and have created the following sieve
script:

        require "fileinto";
        if header :contains ["to", "from", "cc", "bcc"] "fedora-list@xxxxxxxxxx" {
                fileinto "INBOX.fedora-list";
        }
        elsif header :contains ["to", "from", "cc", "bcc"] "linuxdevices.com" {
                fileinto "INBOX.Embedded";
        }
        elsif header :contains ["To", "from", "cc", "bcc"] "nl.internet.com" {
                fileinto "INBOX.Newsletter";
        }
        else {
                fileinto "INBOX";
        }

I installed it with sieveshell and activated it (sieveshell list):

        list
        sieve.bob  <- active script
        
I do not see anything in maillog, but timsieved is running, presumably
because of 

        sieve         cmd="timsieved" listen="sieve" prefork=1

in /etc/cyrus.conf.  I changed prefork=1, it was prefork=0.

Any suggestions?

Bob...
