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.

Myself and a friend have our own small IT business; we mainly design and build web sites for other small businesses.
One of the things we would like to offer to clients is the ability to relay email addressed to their company's domain to their own personal email address (either web-based, or hosted by their ISP).
Now, clearly there is a risk of our mail relay being marked as "open", and therefore becoming black listed as a source of spam. Not something that we want to happen!
Has anyone any experience in setting up such a system? I understand how I would go about configuring an MTA like Postfix or Sendmail to perform such a task, but I'm unsure how I would ensure that relayed mail is delivered and we're not labeled as spammers.
I did wonder if perhaps the "mail forwarding" options in a mail server like Zimbra would get around the issue by forwarding on messages inline or as attachments within new emails (so the messages would appear to be from the account hosted on our server).
When I set up something similar in the past, some messages were rejected by an ISP (BT in this case), because they were seeing messages directed to one of their customers' email addresses, but with a different "to" address to the recipient.
This was implemented using "distribution-list" functionality in the software I was using. Essentially, there wasn't a local mailbox for the user, instead their email was redirected by the MTA as soon as it was received.
I apologise for not being clear enough before, thank you for persevering with me!
Do you have any recommendations for services to use?
I have used AuthSMTP in the past, but that requires that you register all email addresses that you will be sending email from. This is something that isn't possible if I'm setting up a distribution list for a client.
