Ivan-

sync_client looks for the presence of a particular file. If it finds
it, then it shuts down. If you look at the man page for sync_client
it's mentioned as -F option. I suspect that it's there such that you
don't shut down the process while it's replicating an email and then
your replica would be in an inconsistent state.
