MH-sync is a small suite of command-line tools designed to allow an MH user to read mail offline by synchronizing a local set of MH folders with the "real" MH folders online at a remote site. Changes made using 'rmm' and 'refile' will be propagated back to the server site correctly without being affected by "folder -pack" or server-side message filing or removal. ssh is used as the transport, and no other ports need be open on the firewall.
