Discover the main email protocols (IMAP, SMTP, POP)

The computer protocol specifies the rules for exchanging information between two machines. Emails, being one of the main uses of the Internet, are based on a number of communication protocols. The email protocols used to pass emails from server to server greatly contribute to securing your identification data (login and password). Finally, make sure you clean your mailbox regularly in order to optimize the security of your information.

What are email protocols and how to use them?

There are 3 main types of email protocols: SMTP (Simple Mail Transfer Protocol), POP (Post Office Protocol) and IMAP (Internet Message Access Protocol). Outgoing protocols (SMTP) are used to manage the transmission of email between servers. On the other hand, incoming protocols (POP and IMAP) are used to manage the sending of messages to mailboxes. So, they are in a way protocols for receiving and distributing messages.

The IMAP protocol

The IMAP protocol allows you to check emails from anywhere. Therefore, it ensures constant synchronization between your workstation and the server. Thus, your emails are better managed, sorted and classified. When you check your emails, you can ask to download only the headers or the body. This is a convenient solution if you do not want to download unnecessary attachments.

You can also search from the server to see if an email is urgent or not. However, the IMAP protocol requires more resources on the server side and download time can be increased, especially if connected by Modem.

The POP protocol

The POP protocol allows the recovery of emails located on a remote server. It manages the authentication of the account holder via his login credentials. Also, it offers the possibility to consult messages in offline mode. The POP protocol downloads emails to the server and stores them locally.

After authenticating the recipients, it puts the messages on hold. Afterwards, emails can then be sent in bulk to a computer, stored or deleted on the server. However, it should be noted that the POP protocol is not adapted to mobile media and messages are not always synchronized with the server.

The SMTP protocol

It is the most complete of the electronic communication protocols. It is used to forward an email from server to server. Finally, the SMTP protocol centralizes the e-mails sent in a kind of special envelope, on which it places different tags, such as the name of the access provider, the name of the recipient and his email address.
