Rarely Known! This Is The Protocol Used To Send Emails Safely

YOGYAKARTA - People rarely know if there are protocols used to send emails that have an important role in maintaining the smooth and security of electronic messages.

Without protocols, the process of sending and receiving emails will not run well. This is because each protocol has different functions, ranging from sending, receiving, to saving messages on the server.

By understanding how each protocol works, you can find out how the email moves from one device to another quickly, safely, and efficiently.

Reporting from the Site Ground page, there are three main types of protocols used to manage email accounts, namely SMTP, POP3, and IMAP. Each has a different way of working and function, the following explanation:

SMTP is the standard protocol for sending emails. This protocol is tasked with delivering messages from senders to recipient servers, or between email servers.

Well, when you send emails from apps like Gmail or Outlook, it is SMTP that ensures that the message is sent to the destination address.

SMTP works via a connection between SMTP email clients and servers using certain commands. With the help of this protocol, you can send emails from one account using various different email applications.

POP3 is used to download emails from the server to the user's computer. After the message is downloaded, it will usually be deleted from the server, so that the email is only stored locally on your device.

POP3's advantage is that you can still open and read emails offline. However, if you want to save a copy of the message on the server, you need to manually set the option in the email app.

Unlike POP3, IMAP allows you to access and manage email directly on the server without having to download it to the device. With IMAP, all messages and folders are synchronized in real time on all the devices you use.

This protocol supports some users to connect to one email server, as well as allows for quick search, folder management, and tag (flag) of certain messages. Interestingly, messages will only be deleted from the server if you delete them manually.

Then the difference between SMTP, POP3, and IMAP lies in its function in the process of sending and receiving emails.

POP3 and IMAP function to receive incoming emails, so they are referred to as mail access protocols. Meanwhile, SMTP is used to send emails, both from clients to servers and interservers, so that it is known as an outgoing protocol.

In simple terms, POP3 and IMAP help you receive messages, while SMTP allows you to send them.

POP3 is usually used if you only access email from one device, because the email will be downloaded to a computer and removed from the server, thus saving server storage space.

Meanwhile, IMAP is more flexible because it allows access from various devices at once, as well as maintains message synchronization on the server.
