mailx and slackware
 

I've tried putting this as the last line of my rc.local

mailx -s 'Machine booted' test@besked.co.uk

but it does not work. Its works ok from the prompt as root. I even tried putting it into .sh script and gave it chmod 777, but it still did not help.

Any ideas?

try adding the '-r <fromuser>' flag to it

It asks for a subjest?
