Remove old servers
Forces MLdonkey to perform the server list cleanup process. Servers records older than max_server_age days, and servers with IP addresses from server_black_list or ports from port_black_list are removed from the server list.
Server list cleanup is also performed automatically on a periodical basis, so this command is only more or less useful immediately after bp or bs. (Gives you a false idea that you're in control, too. :)
