No appologies necessary. I had to start from the same place too... the beginning. It sounds like you already have a good grasp on it.
In your namecheap control panel, pick the domain you wish to modify, then...
go to modify DNS
and change your setting to Use Namecheap's NameServers
go to Modify Host Records
and modify your domain records.
Here is a link to another thread that will help you setup your DNS records... http://www.webhostingtalk.com...threadid=327475
Before you make any changes, keep in mind that when you switch to Namecheap's nameservers it will take about 24 hours to propagate. After that your changes will be immediate.
Setup the host records or DNS Zone files on your host server as you normally do. Namecheap's nameservers will direct all requests to your primary IP address. The name server on your host server will redirect the request to the correct website based on its own zone records.
Regarding the email settings, for most of my domains I use the User
setting. However, for my hosting company I use Email Forwarding
. There is a short wait sometimes, but if the server my website is on goes down, I still want my email.
If you do use Email Forwarding, make sure you go to Modify Email Forwarding
and set up where you want your email to go.
I hope this answers your questions.
