Purpose:
The purpose of this assignment is to familiarize the student with the working of an internet email system. A working email system is critical for any Linux/UNIX system. Many time you will need to setup the email coming from a local system to relay to a master email server.
This assignment should teach you how to setup the email to properly and with some authentication relay to another email server.
In this case, you will be using one of your public email addresses and it's email server and you will probably use username/password authentication. You may have to change the port on which "sendmail" is run because some ISPs block this information.
