This option should not be used when other message-handling software
may duplicate messages by making hardlinks to the files. When that is done Exim
will count the message size once for each filename, in contrast with the actual
disk usage. When the option is not set, calculating total usage requires
a system-call per file to get the size; the number of links is then available also
as is used to adjust the effective size.
