Mail notifications don't necessarily require a mail server be configured on Linux systems, as LightningTip will also use /usr/bin/mail.
However this tool needs to be setup in some cases to work properly. Usually having a local mail server installed will do this for you, even if just a satellite host, but in some cases you may be required to do it yourself, and the following is how.
You can install the mailutils package as follows
apt-get install mailutils
This will create the symlink /usr/bin/mail -> /etc/alternatives/mail
You can install the mailx package as follows
yum install mailx
You can install the mailx package as follows
dnf install mailx
Test the /usr/bin/mail command is properly installed with
echo "Message" | mail -s "Subject" your@email.addy
