rootのmail fowardができない－３

ふと疑問からCron以外をmboxへ落とさずにmailのspoolへ残したい
場合
[pepo1@~]$ cat .procmailrc
#$HOME/.procmailrc
VERBOSE=on
LOGFILE=$HOME/procmail.log

# Is it coming from Cron If yes, DELETE IT!!!
# Other coming in mbox
:0
* ^Subject.*Cron
/dev/null

# Cron以外の全てmboxへ
#:0
#* ! ^Subject: Cron
#mbox
とコメントアウトしてテスト
[root@~]# mail root
Subject: Test no mbox

[root@~]#
きちんとspoolされとる。。当たり前か
