What is SMTP or Simple Mail Transfer Protocol?
Let’s start with explaining What is SMTP? What is the meaning of SMTP? SMTP stands for Simple Mail Transfer Protocol. It is similar to your Internet Protocol or IP address used to the principal communication network. It is a part of the application layer of the TCP/IP protocol. SMTP works on the concept of “store and forward” just like a CDN. It works with your MTA or Mail Transfer Agent to send your communication to the desired computer or recipient. MTA is basically an SMTP Server. Click here to find out what is an SMTP Server?
SMTP basically controls how the email that you send moves from your MTA to another MTA. The Simple Mail Transfer Protocol provides you with a set of code that makes it easy to communicate emails among the email servers (just like your web servers). SMTP helps break down the message into different parts that only the email servers can understand. I hope we answered the common question that people have in mind what mail protocol is used to send mail messages to a server? The answer is simple SMTP Or simple mail transfer protocol!
Fun Fact – SMTP is able to transfer only text, it can’t handle fonts, graphics, attachments etc. That’s why you call it SIMPLE mail transfer protocol 😛
You use MIME or Multipurpose Internet Mail Extensions to send non-text content like multimedia. In the transformed format, SMTP is cajoled into transferring the data.
The message is turned into small fringes of text. Which can be identified by the servers. SMTP provides the codes to servers which then can be decoded. These messages are sometimes passed through many MTA’s or computers. They get briefly stored in their path. You can think of it like a letter going through many hands to reach its destination.
Fun Fact- Your ISP (Internet Service Provider) have a limit of no. of emails you can send out. Usually a particular no. per hour or per day.
Every ISP relies on its SMTP to govern and determine the number of emails that can be sent by each connection. For some of the persons who need to send a huge amount of emails, this can be a hindrance. To avoid this always check your ISP’s policy.
What is SMTPs? Or Simple Mail Transfer Protocols?
SMTP/SMTPs (Simple Mail Transfer Protocol/Secure or SMTP over SSL): By now you must be well aware of the meaning of SMTP and its role in sending emails. Now let’s move a step further and discuss what is SMTPs? SMTPs is a method for securing SMTP with transport layer security and is intended to provide authentication of the communication partners.

Simple Mail Transfer Protocol is a protocol for the communication of Emails. It was first defined as IS or internet standard in 1982 by RFC 821, then again it was updated in 2008 and it was updated by RFC 5321 to extended SMTP additions which we use even today. As discussed above all the MTA’s use SMTP. It is also used by Proprietary systems like IBM Notes, Microsoft Exchange, and Webmails like outlook, yahoo, and Gmail use non-standard protocols internally, but use SMTP to send and receive emails externally.
SMTP Servers use Port No. 25 with the Transmission Control Protocol
User-level email clients, usually use SMTP only for outgoing messages to a mail server for relaying, and typically submit an outgoing email to the mail server on port 587 or 465 as per RFC 8314. For retrieving messages, IMAP and POP3 are standard, but proprietary servers also often implement proprietary protocols, e.g., Exchange ActiveSync.

How does SMTP server work?
SMTP server Works Exactly on the principle of our typical Mailing system. It collects the sender’s email and delivers it to the recipient’s local post office, which is another SMTP server.
Before proceeding further, let us understand it with a physical mail, suppose there is a sender who lives in Mumbai, and he/she wants to send a mail to a receiver who lives in Delhi. Primarily the mail will be sent to Mumbai’s post office which will act as a sender’s mail server then the mail is being sent to Delhi’s post office which will act as receiver’s mail server and after that, it reaches the receiver.
Similarly, When a sender tries to send mail for example through Gmail to yahoo mail, To complete this process SMTP’s main work is to transfer the mail from the sender’s mail server to the receiver’s mail server. In the end, POP/IMAP is another Receiver server that is responsible for receiving mails and sending it to the receiver end.
You send an email with your PC email client or through the web from your own email address to a particular contact.
The message is commonly sent utilizing port 25 to an SMTP server which is designed in your mail customer.
The client and the server start a concise “discussion” where the server confirms all the data with respect to the transmission of the message such as sender, beneficiaries, domains, and so forth. Note that the SMTP language characterizes just the transmission of the message, and doesn’t watch the content of the message body.
At that point, if space to which the beneficiary has a place has its record legitimately associated with the server, the email is conveyed right away. Something else, the SMTP server conveys the message to another server closer to the beneficiary. In our message, the webserver interfaces with the Domain server, if everything is right then it receives the email and stores it.
What occurs if the beneficiary’s server is down or occupied? The SMTP server just conveys the message to a backup server: if none is accessible, the email is lined and the conveyance is retried intermittently. After a specific period, if the conveyance isn’t effective, the message is returned as undeliverable. Read about email automation tools to increase your sales!
On the off chance that there are no issues, the last fragment is constrained by POP, another convention that gathers email from the receiving server and spots it in the beneficiary’s inbox. We hope we have cleared all your doubts about what is an SMTP or what is an SMTP server? Let’s dive in to learn some more about SMTP servers.
While Sending the Mail, SMTP is used two times-
- Between the sender and the sender’s mail server
- Between the sender’s mail server and the receiver’s mail server.

Most of the users feel that SMTP servers require a lot of expense while setting up. Be that as it may, on second thought, it truly doesn’t. Since each of the SMTP servers has limitations on them to serve mails on different ISPs.
Regardless of whether you do the coding that helps you to scale and send a large number of emails, in some cases Internet service providers(ISPs) Block the emails and treat them as Spam because a single user has sent emails in bulk from the same IP at the same time.

Frequently Asked Questions
How Does SMTP Work?
SMTP is a set of rules which is used for bulk email Transmissions. To make this possible we use SMTP servers to send free emails, which is responsible for transmitting emails from sender to receiver. Let us understand this with a physical example. Suppose you live in city A and your friend lives in City B. Do you want to send a letter to your friend who lives in city B. what will you do first?
You will write a letter and send it to your nearby post office ( Sender Server) From which it will transfer to its destination, i.e Receiver’s post office ( Receiver Server). Now Through Receiver’s post office, it reaches B. This is how the SMTP server works. But one thing you should keep in mind is that SMTP servers are only responsible for sending mails.
