What is SMTP?

Simple Mail Transfer Protocol  or SMTP is just a protocol that functions by relaying email messages from one server to another, allowing emails to be sent across the internet successfully. It is a central component of the internet’s email system. It is mainly used to send emails from an email client to a mail server, which can then relay the emails to another mail server as needed. Let us start with some of its key points so that you get a better idea. 

Functionality

Sending Emails: SMTP helps send emails from one server to another, moving them from the sender’s server to the receiver’s server.

Relaying Emails: It also helps in transferring emails between mail servers and making sure that the email reaches its destination.

SMTP Servers Working

An SMTP server acts as a digital post office, helping with the transmission of emails all over the internet. When you send an email, your email server communicates with your SMTP server, it gives the recipient details, message content and the attachments in the email.

Once the SMTP server processes the email, it routes it to the SMTP server associated with the receiver’s address. Which then stores it until the receiver gets back their email server. This process also involves authentication, verification and attaching many protocols to make sure the delivery is reliable.

Ports 

Servers use ports to manage the transmission of email messages from clients to servers and between various servers. This is why different ports are used and their significance is different as well:

Port 25

SMTP communication typically engage port 25, which is the standard and default port for sending email messages. It is mostly used for server-to-server email transfer. Because it is weak and it is mostly misused for spam, many ISPs block port 25 for any outgoing mail from user machines. This reduces the risks​ of spam​.

Port 587

It is the most recommended port which is mainly used for client-to-server email submission and it allows email users to send outgoing emails to the server more securely. It can use STARTTLS to turn an unencrypted link into an encrypted link. It increases security by avoiding any trespassing​.

Port 465

It was assigned for SMTP over SSL to provide a secure connection right from the start. It is used for secure email transfer from users to servers using SSL encryption. Although it was not approved for STARTTLS on port 587, some email services still support and use port 465 for SMTPS​.

Port 2525

It is an alternative to port 587 which is usually used by some email service providers. It serves as an alternative for email submission when ports 25 and 587 are blocked.

Commands

• HELO/EHLO: To identify the server.
• MAIL FROM: To specify the sender’s address.
• RCPT TO: To specify the recipient’s address.
• DATA: It starts the transfer of the message content.
• QUIT: It ends the session.
