Re: DNS Config?

Ok, the A record relates the domain name to IP address; ie not the url.
1. So does the DNS server (BIND installed on a server) direct the incoming
traffic from the IP to the correct destination (possibly the URL
IPaddress:socket/squirrelmail/src/login.php)?
2. Is it incorrect to install BIND on the mailserver itself?
3. What makes a domain name fully qualified (fqdn)?

What I am trying to do is set up a mail server. I want to type the domain
name in and have it directed to the mail server.  I thought that when I
registered my domain name that I could just direct it to my url through
their control panel, but if I am understanding you correctly I first need to
direct it to my IP address and then the BIND program will send it the
correct URL-- am I completely off base?

Thanks
