POP3 vs IMAP Comparison & How to Setup Gmail using IMAP & POP3
Accessing, storing, and retrieving your email content is a serious business. And serious businesses require one to make a conscious decision.
So, let’s get straight to the point - - which one should you opt for?
What is POP3 vs IMAP?
First off, both IMAP and POP3 are email protocols that have been designed for fetching emails from the server.
To put simply, the emails you receive as a two-part system - the first part being the email client (a program/app that is installed on a computer or smartphone) and the second part being the email server.
Now, for these two parts to work in synchronisation, both the server and the client must agree on a common protocol or standard. And these standards are called POP and IMAP, since they represent a set of common demands that helps email clients and email servers to understand each other.
What is POP3 & How does it work?
The name POP stands for Post Office Protocol. And the POP3 simply means the third version of POP. The names POP and POP3 can thus be used interchangeably. Recently, POP4 was also introduced. However, it appeared only as a mini-extension to POP.
Here’s how POP works:
POP words through a few commands that are passed between email client and email server. Below, I’ll take you through each of those commands and how the whole process works.
- POP command used: USER, PASS, APOP:
Firstly, an email client connects to the server, authenticating through password and username one puts into their account settings. Once logged in, the server mailbox is locked so it becomes inaccessible from another device or computer - a POP protocol here ensures that another connection is now allowed in the meantime current one is in use.
In simple words, the lock prevents two different computers from accessing mailboxes at the same time.
- POP Commands Used: STAT, LIST, UIDL, TOP:
Next, POP examines streams of messages which the server offers and identifies ones that are new. POP can only analyse the contents of your inbox folder message.
