It seems to me that this could be far more easily done by creating a pseudo- user. Have this user be the target of the alias and his sieve script will be run. That sieve script can have nothing but fileinto directives to populate the public folders. This pseudo-user does not even have to have an INBOX, I don't think. Or if it does, then it will be perpetually empty if your sieve script is written correctly. :-)
