Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

My Linux experiance is very minimal. I took over monitoring of a network about a year ago which uses the Nagios system. Everything has been working perfectly and I've done a number of changes within Nagios and its hosts.
Heres the problem... We recently moved the hosting of our domains to a different company. After moving the Nagios email notifications also stopped. I have realised that the domain that the Nagios was emailing from was not moved over and since it was only being used by the nagios it has been tossed. I now need to setup the mail to mail me from a new email address for notifications.
Unfortunitely I do not know enough about the linux email system to do changes.
The email commands in Nagios looks like this:
command[notify-by-email]=/bin/printf "$OUTPUT$" | /bin/mail -s '$SERVICESTATE$ alert for $HOSTALIAS$/$SERVICEDESC$' $CONTACTEMAIL$
command[host-notify-by-email]=/bin/echo -e "***** Nagios *****\n\nHost "$HOSTALIAS$" is $HOSTSTATE$!\n\nDate/Time: $DATETIME$\n" | /bin/mail -s 'Host $HOSTNAME$ is $HOSTSTATE$!' $CONTACTEMAIL$
So from this it seems that it is using the /bin/mail app to send the mails, so how do I edit the originating email address & password?
