Newbie to MAndriva server

[navop]

Trying to install a mandriva server following the How-To Perfect Server and I
have a few questions

On page 3 where you identify your ethernet connection manually, it asks for a hostname, What should i use their, I do have a domaine name registered, its

www.bidou-electonique.ca, so can my hostname be bidou-electronique

My next question and final one is on page 5 (make sure that you use the correct values for mydomain, myhostname, and mydestination)

what values sho i use for the following mydomain, myhostname, and mydestination

Thanks for all the help

Usually there is a host i.e. computer behind three letters www which serves web requests. This computer in turn has an IP address and human given name - hostname. So in your case it could be say "server01". Actual domain name to which belongs this computer is "bidou-electronique.ca".
"mydestination" describes for whom you're receiving mail - all users in domain "bidou-electronique.ca" would be my first guess.
Things like how to find computer's name, related IP address, alias name(s) for certain hosts (computers) are maintained by DNS.
I would suggest reading "bind" man pages and related how-to's since if your'e setting up mail server you will be dealing with it very soon.
So far my attempts to find IP address for www.bidou-electronique.ca via http://www.all-nettools.com/toolbox SmartWhois function are unsuccessful.

Good luck!
