Apply Sieve script to messages already in INBOX?

I had thought of doing this using the sieve-test utility provided with 
cyrus, which lets you specify a message + sieve script and prints to stdout 
the actions that would have been performed.

The only issue is on large folders having to retrieve lots of messages and 
run the utility lots of times. I just thought it would be easier to get the 
server to do it and just pass back the actions that would be performed.
