In present times, continuous advancement of technology has taken the world by storm. Not only has it influenced the medical and other such important fields but also the daily life of every individual one way or the other. Internet is one such technology that has made our life simpler in different ways. Earlier, when we needed to keep in touch with our loved ones, we had to write a letter and then post it. Also, there was no guarantee that it would reach the recipient on time. Thus, with the introduction of e-mail, all these shortcomings have been overcome. When we send an email, SMTP mail server comes into play. Thus, this SMTP service is responsible for sending and receiving e-mails.

SMTP is a short term for Simple Mail Transfer Protocol. E-mails are the fastest and easiest form of online communication. When we send an e-mail, the SMTP mail server first searches for the domain with the particular e-mail id. When it finds the id with the recipient name, it sends a message to that particular server about the mail. Once the recipient SMTP mail server confirms the mail, it will accept it. All these procedures take place in a few seconds. When we send an email, we just have to press the 'send' button and our mail is sent to the specified id. Thus, in order to send and receive e-mails, installing SMTP is a must.

Before you install the SMTP mail server, there are some points which you have to keep in mind. First, make sure that all the system requirements needed to install this server are available in your computer. This is a very important point to note because if the essential software requirements are not fulfilled when installing the SMTP server, it will not work properly. Once you have installed the server, test it to confirm whether it is working or not. To know whether the SMTP mail server is working or not, make a connection to this port. If the server is correctly installed, on the screen you will see the specific domain name along with the date and time. After this step, create a sample e-mail to test.

Once you have created the headers for your e-mail hit the '.' to end composition. After this step send the mail into the delivery queue. Once your sample mail is queued for delivery by the SMTP mail server, you can 'Quit' to exit the telnet session. The mail usually sits in the queue until the server forwards it to the recipient. Thus, if the recipient receives your mail, it means that you have successfully installed the SMTP mail server. If you have installed it, it is imperative to test it so that you do not face any problems in future.

The SMTP mail server is not only essential to communicate with our loved ones but also plays a vital role to expand any form of business. With the popularity of e-mail marketing, several companies are adopting this approach to advertise their products and services to customers all around the globe. In this method, companies sent the advertisement about their products and services to potential customers through e-mail. Thus, the SMTP service helps these individuals to take their business to the next level.
