Help with sieve

[Joy]

Dear Experts,
                     I am having following script which is working
perfectly on 3 server but not working as expected on new server.

I have updated latest sieve software compiled from source, In case i use
fileinto to move mail to other folder it works perfectly ..



require ["fileinto","imap4flags","envelope","body"];

}
