Maybe you can add a rc script to send an email at shutdown.
For example :
===============/etc/init.d/notifyhalt========================
#!/sbin/runscript

EMAIL="root@server.net"

depend () {
	need net
}

start () {
	return
}

stop () {
	ebegin "Notifying $EMAIL of rebooting the system"
	cat <<EOF  | sendmail $EMAIL
From: halt.notify@server.net
Subject: System reboot

The system is rebooting !
EOF
	eend $?
}
===================================================
Add it by rc-update add notifyhalt default
Hope this can help !

I tried this. Usually this e-mails won't sent until the server up: my system
hats fatser than mail sends. You may add delay, but as for me, this is bad
solution.

Hi,

I would rather suggest you put the code into

	/etc/conf.d/local.stop

That script is executed before anything in /etc/init.d is stopped.


If you want to make sure the mail has left your system, you might 
test if the outgoing mail directory is empty. In my case that is

	/var/spool/postfix/active

One way to wait until the directory is empty would be

    while [ `find /var/spool/postfix/active -type f -mmin -1` ]
    do
        sleep 1
    done

Actually, the "-mmin -1" will make it wait at most one minute.

Or you wait at most 3 seconds, like this:

    find /var/spool/postfix/active -type f -mmin -1 && sleep 1
    find /var/spool/postfix/active -type f -mmin -1 && sleep 1
    find /var/spool/postfix/active -type f -mmin -1 && sleep 1


Regards
Stephan

Hello Stephan Wacker,

>     while [ `find /var/spool/postfix/active -type f -mmin -1` ]

find returns success if it finds no files, so this will loop forever. Use [[ $(find blah | wc -l) -gt 0 ]]
