Domain Names

What is the Domain Name System?

The Domain Name System (DNS) helps users to find their way around the Internet. Every computer on the Internet has a unique address 굳t like a telephone number 稩ch is a rather complicated string of numbers. It is called its "IP address" (IP stands for "Internet Protocol"). But it is hard to remember everyone's IP address. The DNS makes it easier by allowing a familiar string of letters (the "domain name") to be used instead of the arcane IP address. So instead of typing, you can type It is a "mnemonic" device that makes addresses easier to remember.

Translating the name into the IP address is called "resolving the domain name." The goal of the DNS is for any Internet user any place in the world to reach a specific website IP address by entering its domain name. Domain names are also used for reaching e-mail addresses and for other Internet applications.

POP mails - Point of Presence email storage facility (also known as Post Office Protocol)

PPP Internet access required to read or send e-mail. This means you will need to have a dial up account to connect to the Internet with your local ISP (Internet Service Provider). You will also need to use your ISPӍTP address to send mail. When setting up a program to get and receive mail, you should be able to put our address in the POP setting and your local ISPࡤdress in the SMTP setting.

There are two versions of POP. The first, called POP2, became a standard in the mid-80's and requires SMTP to send messages.  The newer version, POP3, can be used with or without SMTP.


Something newer than POP is IMAP, for Internet Message Access Protocol, a protocol for retrieving e-mail messages.  The latest version, IMAP4, is similar to POP3 but supports some additional features.  For example, with IMAP4, you can search through your e-mail messages for keywords while the messages are still on mail server.  You can then choose which messages to download to your machine.  IMAP was developed at Stanford University in 1986.


SMTP (Simple Mail Transfer Protocol) is a TCP/IP protocol used in sending and receiving e-mail.  However, since it's limited in its ability to queue messages at the receiving end, it's usually used with one of two other protocols, POP3 or Internet Message Access Protocol, that let the user save messages in a server mailbox and download them periodically from the server.  In other words, users typically use a program that uses SMTP for sending e-mail and either POP3 or IMAP for receiving messages that have been received for them at their local server.  Most mail programs such as Eudora let you specify both an SMTP server and a POP server.  


By default, all e-mail addressed to your domain is forwarded to the default mail address, which is, your user name.  If your user name is Joe and your domain name is, your e-mail address would be  As such, e-mail addressed to will be forwarded to your "default" e-mail address.  An alternative is to have mail forwarded, using .domains with our UNIX servers, IMail from IPSwitch, or to retrieve mail from POP3 mailboxes.

Use the following settings to configure your mail program to access the master POP account:

   POP Account:    <username> 
   SMTP Server:    (use the SMTP server provided by your ISP), for example,

Substitute your account userid above. Your master POP account password will be the same as replica watches uk your web account password.

Please be advised that the master pop account will reside at /var/mail/ directory as a text file just like the other additional POP accounts that come with your website. Keep in mind that all POP boxes count against your disk space.

Configurable POP Accounts

You can also choose to set up POP Accounts for specific e-mail addresses. For example, e-mail addressed to could be held in a private POP mailbox and be accessed with a unique ID and password.

Let's say you want to rolex replica use "" as an address at your site. Because the user name "webmaster" is reserved for the server, you can't use "webmaster" as your user name, but, you can forward e-mail sent to "" to a unique user name that you choose. Follow these steps:

  1. Create the unique user name which becomes a new POP account. Use the online form
    Enter the user name of the new POP account (this is not necessarily your user name - make up something new if you like).  A password - 8 characters long, will be chosen for you.
  2. Once your new POP account is set up, you will notice an additional line in your .domains file located in your root directory /mnt/web/guide/yourdomain/ newname # # # # yhr yhr
  3. Simply change this line to read: newname

   SMTP Server:(use the SMTP server provided by your ISP - for example,

Please Note:
The User ID for additional POP accounts is NOT the same as your account userid. You need to assign unique ids and passwords for access to the additional POPs for privacy.


Remote Access

When accessing your e-mail from multiple computers, you must determine whether or not you need the ability to view all your mail at all times. For example, if you check your e-mail from your home computer, the e-mail cannot be viewed from your work computer. In order to view all your mail from multiple locations, your e-mail software can be changed to keep a copy in your mailbox. This will allow you to access all your e-mails from different computers.

1 - Open Outlook, click the Tools menu and select Accounts.   2 - Select the Mail tab.   3 - Highlight one of the accounts displayed in the Accounts window and click the Properties button.   4 - Select the Advanced tab.   5 - Under the Delivery heading, check the box Leave a copy of messages on server.  This option will store a copy of all your e-mails on the mail server.   6 - To avoid exceeding your mailbox storage limit by storing outdated e-mails, you can also check the box to Remove from server after __ days. This will allow you to set the number of days that e-mail will be stored on the mail server.

E-mail is completely removed when the trash folder is empty.


Servers / Clients

The data used on the Internet is delivered by servers. There is an email server to handle your email, an FTP server to transfer files, and a Web server that delivers webpages so that you can view them on your computer. Your browser is the client, and the remote computer is the server. It is only by convention that these servers are named www, but they can be named anything. Lately, there have been websites that eliminate the WWW and just use the domain name. It is the http:// that tells your browser it is Web traffic. It then asks the server for data on a specific port. It is presumed that if you are using a browser, you are using Web traffic. Http defines how to format and transmit the data and what actions the Web servers should take in response to various commands.
