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.

Hi, we have postfix setup on a centos box as an smtp relay, so I setup relay_domains and transport maps to relay emails addressed to our domains to our mail servers. We are using postini as anti-spam, so I'm not really worried about spoof emails. However, I forgot to add a rarely-used domain to the transport map, and an email addressed to that domain bounced. We received a bounce email, but this is what I'm confused about. The email address that received a bounce notification is email@example.com, which is actually where we want it to go, but I never set up that email address. I set the postmaster alias in /etc/alias to be my personal email address, and in main.cf there are no bounce configuration lines (which I'm assuming means it uses the default postmaster account). I'm confused about how it got sent to the support email address? Googling just keeps showing me the alias files, it doesn't really explain how postfix could be sending it to that particular email address. Thanks for any light that can be shed on this matter!
Did I do this incorrectly? Do these have to be system accounts, and if so, how can I have it so that alerts sent to postmaster are forwarded to my email? And this still doesn't explain how the emails are getting sent to firstname.lastname@example.org when the default bounce should be sent to postmaster??
also, the rest of /etc/aliases hasn't been changed, so it's still support: postmaster
I thought I did, as well as newaliases, but I'll run those commands again. In the meantime, I just want to confirm that you can in fact write out the email address for the postmaster: alias? Everything I see online shows the postmaster: alias set as a local system account, and then forwarding the emails? This kind of confused me, but is this doable?
That's what is confusing to me...how/why did the notification email get sent to email@example.com in the first place??? I sent an email that I knew would bounce, as a test, and I haven't received a notice yet. I sent it yesterday, the last one took about 3-4 days to come so it may take that long for this as well. I'm just confused by that email. I haven't received anything at all at my personal address, which is what I set the postmaster alias to be!
