I am in the process of setting up nagios core, problem is I am fully windows based. So far I have even impressed myself with the knowledge obtained.

However linux is not windows that's a fact. I am struggling to fully configure nagios core to send automated email notifications to myself or a distribution group.

anyone that can assist as I don't have a clue what's next.

Hello & welcome to LQ.
That's why I use it.

Have you tried looking here: http://library.nagios.com/library/pr...score/manuals/

Before Nagios (or ANYTHING) can send emails out, you have to configure your mail services, just like you would have to on Windows. You don't say what version/distro of Linux you're using, but chances are you've either got postfix or sendmail installed. You need to configure mail services to have a smart host/relay server. Without knowing which version/distro of Linux you have, we can't tell you how to check which one you've got.

You say nothing about your environment, but assuming it's for a business, you've probably already got a mail server in place. Tell your existing mail server to accept and relay messages from your Linux/Nagios system. From there, it's a fairly easy process to point your Linux system to the other mail server.

So, a few details from you, and we can help.
