Commands: newcode Format: newcode Randomizes the code number for the currently selected list. The actual name of any mailing list is "listxxx-yyy", where "xxx" is an internally-assigned number that is guaranteed to be unique across the set of lists present on the system. If a user discovers the code number and the inode number, that user can circumvent listmanager's privacy and security checks, and broadcast to the list. This is not really possible since sendmail strips that information away from the headers of outgoing submissions, and the command is really only present for historical reasons, and "just in case". This command is only available to list owners. See also: newaliases select
