How to I configure UNIX mail to e-mail messages to external addresses?
I've got a shell script that has to watch a process to make sure that it does not die... if it does it mails root with:
mail -s "Service is down!!!" root
I would like to get this going so I can inform management when the process dies by sending that message above to a completely external e-mail address.
What should I use to get this going the best?
