Heartfelt thanks to the Internet that has emerged to be one of the best tools in making lives easier and simpler. Whether you are looking for some information or communicate with someone, it’s the online connectivity that makes everything possible. The craze for using the internet services in solving diverse problems is undeniably stunning. In fact, the majority depend today on the emailing technology today to get in touch with near ones instead of doing the same through phone calls. Now, installing any web browser in your laptop cannot help you send bulks of mails to your clients. It’s the Simple Mail Transfer Protocol or SMTP that has emerged to be one of the most effective mail delivering servers in these last few years.

The popularity of computer and later the internet didn’t popularize to that extent. In fact, these technological innovations made way to only the top professional houses and was taken into consideration solely for official purposes in the beginning. Gradually, people started becoming curious to know the usages and specifications of computers. However, the impact was more powerful with the advent of the internet especially the emailing technology. With the wink of an eye, this widespread technology proved to be the most effective communication tool.

The primary aspect that makes SMTP stand out is that it ensures that the mails delivered to people would reach the specific locations with efficiency. A few steps are involved that make communication possible between two PC users. As soon as the sender presses the 'Send' button appearing on the e-mail dialog box, the message gets delivered to the recipient’s server. Once done, the server checks the DNR or Domain Name Registration of the other machine and attempts to authenticate the address specified by the sender. Once validity is confirmed, the server of the sender reports to the SMTP server of the recipient about the pending mail or message which to be received by him.

Today, the SMTP technology has come up as a super development for over thousands of businessmen. With this advanced technology, communication has been bettered and people can now send bulk of mails at a time. This means that all complex tasks can be carried out with efficiency. The introduction of SMTP service has let people get rid of all the traditional and time-consuming concept of letters.

Just after the recipient’s SMTP server receives the message in his computer, a mail being instantly generated is sent to the sender that actually confirms the successful delivery. This very process followed by the server once the sender clicks the 'Send' button. Be it a personal or professional mail, you can be rest assured that it would successfully reach your recipient without any obstruction. With the help of several commands, the SMTP functions work correctly thereby making the overall communication effective.

It has been found however that SMTP commands often turn ineffective in ensuring pinpoint delivery of bulk emails. Therefore, a better and advanced emailing technology has been introduced in the name of ESMTP or Extended Simple Mail Transfer Protocol. The commands here are used to assure that countless emails are delivered to customers with perfection. This betters SMTP service and makes it as one of the most efficient marketing tools for businessmen.
