How to specify where root email goes

Your server sends out a lot of email to user root. For example, CSF (ConfigServer Security & Firewall) sends out most security notifications to root.

So, this is how we specify what email address root emails go to:

vi /etc/aliases

Scroll to the bottom,  and add or replace  existing:

root: YOUR@EMAIL.COM

Save and exit, then reload the aliases:

newaliases

Another option is to create a ~/.forward file and put your email address in it.

Example: Say I'm logged in as root.

vi ~/.forward

This will create (or edit an exising) file:

/root/.forward

Next we add the email address we want root emails forwarded to:

YOUR@EMAIL.COM 

Now restart exim.

service exim restart

And that should do it. 

BTW, you may want to think about what email address you'll use for this, as you'll likely start receiving a ton of emails.
