Nagios Support Forum

Hi All,

I am not receiving the alert notification from my Nagios XI server.

When i tried to send a test notification mail from the console, i got the below error message.

"Mailer said: Could not instantiate mail function. (method=sendmail)
An error occurred sending a test email!"

Can someone help me on this.

Thanks & Regards,
Prabaharan

It may be easiest to configure your machine to use SMTP and an external mail relay as opposed to configuring sendmail on your local server. There are a few steps involved. I recommend reviewing this document:
