Before you know the email should come to know yourself before mbox mailbox or mailbox is a mailbox of its own. Once the user has a floating or at the tells on the Internet. Mailbox will receive automatically. This mailbox is stored on a letter sent to us. So when we started using the machine at any given moment. It will open a mail box that was kept in a box or not. The letter can be found. When you are finished moving out of the box, or to deposit the first time. The fact that virtual mailbox mailbox messages on the machine. And private individuals only.
Usually when we are using the Internet address of a reference to the name on the Internet. And we can set an email address as somsak@nwg.nectec.or.th. This name has two parts: the front and behind the front: the mailbox. Which can be considered as a mailbox. The user name is owned. The mailbox store that has a name. This is the part after the @ is nwg.nectec.or.th.
What is your e-mail
When you start an Internet network. One thing you get is the name of the user on the machine, either as a primary machine, you have a user name. So if you have the address on the virtual machine that is located on the Internet. The Internet address of the machine is configured with a domain name like nontri.ku.ac.th. Refers to the network nontri ku.ac.th which means the network of university education in Thailand. For example, if a user is b38bmx code, it means that you have an address. b38bmx@nontri.ku.ac.th. The name is a reference to the world. Anywhere on the Internet can send a message to the route. b38bmx@nontri.ku.ac.th. For sure.
Therefore, the address that has been so defined as a user on the machine on the Internet. This name will be used for reference. To print business cards for others to come, so it is possible. And references all across the Internet.
Receive e-mail protocol used between the SMTP.
The Internet protocol TCP / IP as the interface between the TCP / IP is set to transmit data between a sending and receiving mail (mail) is an SMTP SMTP stands for Simple Mail Transfer Protocol SMTP was designed. to have an automated mail that is to say that you are working on a program to send and receive mail. Works as a daemon process. (Blacktown ground work process is running all the time) to make and receive e-mail programs such as smail or sendmail do I send mail. If electronic mail is sent. I also do not have contact with the destination. It is a message first. Wait a few hours, it will again. Repeat until the completion of this CMP. If this is not in three days I will return to the owner. The reason for this is not.
SMTP protocol is a protocol for transmission of electronic mail on the Internet. Thus, if the other networks. Such as network traffic with Microsoft msmail msmail program has its own protocols. To access the Internet must be converted into before the change in the SMTP protocol called SMTP gateway.
How do I find the path to the mail on the Internet.
The electronic mail address has been assigned a specific individual mbox on a primary machine. The route is defined as a hierarchy by using a name like s38bmx@cc2.cpe.ku.ac.th. The route from. Th the country. Ac ku is defined as an institution is the Department of Computer Engineering, Kasetsart University cpe cc2 is the main computer of the Department of s38bmx is mbox in cc2.
Assuming that there is a letter sent from America to come to s38bmx@cc2.cpe.ku. Ac.th initially be sent through a gateway into the country from the uunet when it came to Thailand to find a domain name which provides ac. . th at Chulalongkorn University. Would be to apply for a ku.ac.th the path to the University. Then he asked for the domain name services. At Kasetsart University. Stored on the machine nontri nontri to the machine after it is cc2.cpe full path from the source to cc2.cpe.
See that the Internet is the backbone of the location of the machine with the domain name service called DNS (Domain Name Service) the Service will be offering a position on the domain in which self-care. The ac.th care by the ku.ac.th chukn nontri care by calling a method that is called a hierarchy. It's not hard to locate.
The importance of the mail client.
To provide users with easier to use. The mail client program such as mail programs on DOS on Windows. These applications will allow users to more easily use the pine program for Windows. Internet applications, such as clients, has developed a number of companies. Focus is a program that allows a PC linked to the core. And use direct mail. By connecting to their mail box.
Electronic mail is a very important role and one of the applications on the Internet. All users at least have their own mail box. The mail between them. When the number of users increased communications via electronic mail, it will be more. I believe that the future of the world's population will be using electronic networks. The communication by electronic mail. The message is delivered. Many people call it snail mail. Or lowtech mail.
