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.

You can use other SMTP relays those are free and do not need authentication for relaying. You can search google for such. Or else you can use other mail services that you may have account with. Using a free relay is one option but I have never used one of those so I can not guarantee if mails from free relays are treated secure or spams.
i think so. but i guess that also won't cause the error right? i'm just baffled as to why the error i got at home and in school is totally different when both settings are the same? i'm using the same file for both x.x
Hey by the way, are there any ways to solve this kind of error:
Aug 5 06:15:04 ubuntu postfix/smtp: 1AA8540A58: to=<email@example.com>, relay=gmail-smtp-msa.l.google.com[220.127.116.11]:25, delay=1.6, delays=0.05/0.03/1.4/0.19, dsn=5.5.1, status=bounced (host gmail-smtp-msa.l.google.com[18.104.22.168] said: 530-5.5.1 Authentication Required. Learn more at 530 5.5.1 http://mail.google.com/support/bin/answer.py?answer=14257 g4sm354955wae.2 (in reply to MAIL FROM command))
no connection refused error, but authentication required.
Then check all the parameter options in main.cf that relate to authenticating to external relay. What authentication method are you using? What options and all. Make sure you are not sending password as plain text.
The password will be stored in plain text in the file before it is hashed. But how it passes over the network to the server is what I am talking about. smtp_sasl_security_options=noanonymous,noplaintext is what I am talking about.
Also make sure tls method is enabled.
I can not think of anything else.
