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.

Are you trying to send mail using an account with a domain other than your own?
For instance....your machine is using myredhatbox.com, but you are attempting to use another domain to send mail, like email@example.com?
If this is the case, you will not be able to send mail.
Virtually all SMTP mail servers are configured to reject mail on this basis to prevent spoofing/spamming.
I've sent mail with my domain.
my domain is example.com, and my mail server name is mail.example.com.
I set relayhost=mail.example.com.
I've tired to send mail from firstname.lastname@example.org to email@example.com and I can't. I think it is possible, but i don't know why doesn't work?
Must I set the relayhost in my case?
I've just found out that I can't receive mails as well .
I don't know what is happening at me, but every mail (incoming, outgoing) is bounced of my mail server except the local mails.
What is the problem?
Has anybody an idea?
Distribution: OpenBSD 4.6, OS X 10.6.2, CentOS 4 & 5
gubak, you started three seperate threads for the exact same problem. Please do not do that! It scatters the answers over multiple threads and makes it much harder for people trying to help you. I've merged all three threads together now. If you have any more questions about your issues with Postfix and e-mail, please post them in this thread.
