What is the difference between POP and IMAP?

What is The Difference Between IMAP and POP protocol? If you are not sure whether you want to set up your email using the IMAP protocol or the POP protocol, then you can refer to the following differences between these two protocols, and choose the one that best fits your needs.

The e-mail protocol is the procedure which your e-mail program will use to communicate with the server on which your e-mail messages are stored. Currently there are two ways to receive your mail from Toolkit Websites e-mail servers: IMAP and POP. Following is a short comparison of major differences between the two.


The IMAP protocol, by default, allows the user to keep all messages on the server. It constantly synchronizes the e-mail program with the server and displays all present emails. All the actions performed on the messages (reading, moving, deleting...) will be done directly on the server.

Because everything is kept and managed on the server, the user will be able to access the e-mails in all server-based folders from any computer in the world (as long as they're connected to the Internet!) and will always find the same content in their e-mail account.

Because there is a quota on the e-mail servers, it is necessary to regularly delete unnecessary e-mail messages from the server, to avoid problems.


The POP protocol, by default, is set to download all the messages from the e-mail server onto your computer. This means that all the actions performed on the messages (reading, moving, deleting...) will be performed on one's computer.

Once e-mail is downloaded it can be accessed only using the same computer.

Because everything is kept on the users computer, the user will not be able to reopen messages from any location other than the computer where the messages have been downloaded.

This configuration will have to be setup on each computer you wish to use this feature.The client is not limited by the amount of free space on the server. The limitation is the size of the hard drive on the personal computer.
