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.

That's a bit unclear to me too. I have a relay server running here and it only has its own server.domain.es listed and no reference to our domain at all. And it works perfectly. As far as I know that server name will be used when sending/authenticating with other MTA's. In my opinion you can put about anything you want in there, since your mail is coming in through your ISP. Thus, as far as I know, you don't need to buy a domain name.
I'm sure that other LQ users with more knowledge about this will kick in and correct me if I'm wrong (at least I hope so, then I would learn something more too).
All nice and well options given for MAIL IN, but he also asked for mail OUT, the reverse path..
For sending out mail, through you ubuntu server machine, you need to use a MTA (Mail tranfer agent) package, examples of such mta's incl.: sendmail, or postfix, qmail, exim etc etc..
You can also use spamassassin with either MTA, configuration strongly depends on the MTA in use..
Thunderbird will connect to the MTA for SMTP (or SSMTP)
to send out the mails..
The MTA on his turn queues the mail, so the spam detector (e.g. spamassassin) can review the queue, and then signals the MTA to start sending (this is all done within a matter of seconds, depending on the hardware).
NOTE though, some isp's have a smtp gateway in place, meaning they block port 25 (smtp) from the outside world, directly to the client side.
In such case, you need to configure the MTA to use the gateway.
