Nagios Support Forum

This is such a n00b question.....
The /var/spool/mail/root file is growing larger every day. I'm assuming that the messages in there are important or they wouldn't be sent. Is there some way I can forward them to another account? Is there a mail reader buried in Nagios XI for this? Or is it safe to ignore the generated mail?

comfortable.

Scroll down. Close to the end of the file, you should see something like
this:
Type your e-mail, so it will look like this:
Save the file and type in terminal:
Hit "Enter" to apply changes.
