What is the difference between the POP and IMAP protocols?
There are two ways to check for incoming mail, POP (sometimes called POP3) and IMAP (sometimes called IMAP4). Both protocols handle the same tasks, but they approach the process from different perspectives.
POP is the oldest protocol and it was designed in a time when space on the server was very expensive and most people only had a single personal computer. By default, POP connections try to download all of your mail to the local computer and then delete the message from the server. POP connections can keep mail on the server is configured to do so, but most clients don't handle connections that way by default.
IMAP is a somewhat newer protocol that came out when the cost of server time and storage came down a lot. IMAP defaults to synchronizing mail between the server and your local device or machine so both locations match. IMAP can download and remove mail from the server just like POP does, but it isn't configured to do that by default.
POP:
Pros:
1. Downloads email from the server and stores it locally (except on most mobile devices) which frees up disk space on the server.
2. Can view downloaded messages when offline.
3. Attachments are downloaded locally for easier access.
Cons:
1. Since mail is downloaded and removed from the server, if you try to access your mail from another location, you won't have access to your old mail.
2. Your mail provider might have a limit to the number of POP connections per hour because these connections can have more overhead than IMAP connections.
3. If your local machine crashes or has hardware issues and you don't have backups, you could lose your mail.
IMAP:
Pros:
1. You can switch between an e-mail client and webmail at any time and still have the same messages.
2. Makes it easier to access your e-mail using multiple devices because the messages are not removed from the server.
3. Because IMAP connections don't have to download message bodies or attachments until you read the message (if your mail client is configured that way), you can save some space on your device.
Cons:
1. Your mail is only available on the server, so you may not be able to interact with old messages if you are unable to connect to the internet.
2. In the event of catastrophic server failure, you could potentially lose your e-mail.
3. Email folders are stored on the server and may appear differently on different devices.
