I am trying to start 3 scripts at the time my machine boots. I have added the following to my /etc/crontab file but the server does not start any of them when it boots:

@reboot /usr/local/bin/fwconfig
@reboot /usr/local/bin/mailgraph-init start
@reboot /usr/local/bin/postgrey --inet=10023 -d

Anybody who can help out?
