Nagios Support Forum

Thanks, I am using Postfix. I looked at the logs and forwarded the information to my email admin. It looks like my Nagios server is trying to connect.

I am new to this forum and Nagios core. I have not been able to set up email notifications. I have followed some instructions I followed online but I still have not been able to get email notifications. Where can i find comprehensive instructions for this. I am using Ubuntu server 16.04.
