subject: Smtp Mail - The Quickest Way To Connect [print this page] In an age where Internet is a cardinal medium of globalization, SMTP mail and SMTP server is the in thing. It has become almost a household term now. Previously reaching out to people would be such a long drawn process but now its only a matter of flexing your finger muscles. You can travel around the globe and talk to any one at any point of time with just a click.
The process of electronic mailing is conducted by the SMTP server. When a mail is sent by you it passes through various different computers before it actually reaches the targeted or desired person. The first halt of your e-mail is at an SMTP server. The function of of this server is to directly communicate with your machine using the protocol named SMTP. The full form of this abbreviation is simple mail transfer protocol. It is a sine qua non as far as electronic media of mailing is concerned. The principal objective of this protocol is to efficiently, easily and reliably transfer mails from the sender's machine to the receiver's machine. This protocol system only requires data connection that is can be relied upon.
The port that is generally used to communicate with the world by SMTP server is TCP port 25. Nowadays, other ports like port 2525 are also used. The function of these ports is to connect the computer of the client concerned with the SMTP server. This protocol also constitutes certain commands that are used by the client and the server as a mode of communication.
The mail sending procedure may be a matter of a few seconds but the inside story might as well surprise you. The SMTP server receiving your message is just the beginning. Once your message has been successfully sent to the server, it then searches out the recipient's mail server and transfer it there. To locate the recipient's server, first the domain name(that is data that follows the @ symbol) is located. It is then searched with a domain name server, finally spotting the recipient's server. It is after this that a link is established between your mail server and the recipient's mail server. The SMTP mail is then forwarded to the recipient mail server. The mail sometimes does not get delivered immediately. This may be due to technical problems that have occurred at the recipient end of the string. Such a situation is generally handled by sending the message to the sent-mail queue. The sent-mail then tries to resend the mail time and again at regular intervals. The interval may be of 15 minutes. After trying for at-least 4 hours it will generally send you a mail intimating you that some problem has occurred. This process continues for 5 days at the most, after which the send-mail configuration returns the undelivered mail to you. In case the SMTP mail has been successfully delivered, it will be stored in the POP3 server of the recipient, and finally be viewed by the recipient in his or her in-box.
Hence, now that you have been educated on the process of SMTP mail, it must be clear to you exactly how easy your life has been made with the advent of Internet. The apparently easy looking process of mailing is actually a complicated process that is executed by the SMTP server, making communication convenient for you.
