For professional use, internet ISPs, organizations, networks, hosting providers, email providers, or commercial spam filter providers, synchonize option is available.

To synchonize the lists use RSYNC.
Rsync is a fast file copying tool. It can copy locally, to/from another host over any remote shell, or to/from a remote rsync daemon. Rsync finds files that need to be transferred using a algorithm that looks for files that have changed in size or in last-modified time.
