If your computer fails you may lose all your email. The advantages of IMAP are: Messages are stored on the server and are not affected if your computer fails. Easily use multiple computers or e-mail programs to read mail. All mailboxes are MB in size by default. You can allocate more quota to individual mailboxes using the Email Quota Manager in the HostAway Members Panel and if required you can purchase more assignable quota.
Please be aware that unless you purge or archive older emails your IMAP account will continue to grow in size over time. When you send email from some devices it may not save the sent message to your IMAP account by default eg.
An iPhone saves this locally by default. Once it's successfully connected, it grabs all the mail on the server. It then stores this mail locally on your device so you can access it in your email client. Finally, it deletes the mail in question from the email server before disconnecting.
This means that the messages then only exist on the device you downloaded them to. Note that while POP will delete mail from the server by default, a lot of POP setups allow you to leave copies of your email on the server. This can be useful if you're worried about losing your mail, but if your mail provider doesn't offer much server space, it can cause you to run out quickly. After it connects to the email server, it fetches whatever content you requested, like all new email or the contents of a specific message.
This is cached locally, so you can work on your device. Once you make changes to your email, such as deleting messages or sending a new email, the server processes and saves these changes, then disconnects.
You aren't downloading local copies of all your messages; you're using the email client to manage the email stored on the server. The only information stored on your device unless you explicitly download something are cached copies for efficiency.
POP was designed for a simpler time when you only needed to access your email from one device. In those days, constant internet access also wasn't common, so POP made sense for dial-up connections where you got online, did what you needed, and then disconnected. It thus has the following pros:. POP has some advantages in specific situations, but it's largely outdated today.
It's not designed for checking email from multiple devices, so you can experience problems even if you leave a copy of email on the server. For instance, if you delete an email on one device, that deletion doesn't sync to the server, so other devices will still have that message. And since each device downloads every message from the server, it's easy to end up with a bunch of duplicates and not know what you've already dealt with.
Downloading every message from your POP account can use up a lot of space on your device, depending on how much mail you have. In POP3 the mail can only be accessed from a single device at a time. Messages can be accessed across multiple devices To read the mail it has to be downloaded on the local system.
The mail content can be read partially before downloading. The user can not organize mails in the mailbox of the mail server. The user can organize the emails directly on the mail server. The user can not create, delete or rename email on the mail server. The user can create, delete or rename email on the mail server. It is unidirectional i. It is Bi-directional i. It does not allows a user to sync emails. It allows a user to sync their emails.
