Below is an explanation of the general difference between the IMAP and POP3 email protocols.

IMAP Account
Using this protocol, all your mail stays on the server in multiple folders, some of which you have created. This enables you to connect to any computer and see all your mail and mail folders. In general, IMAP is great if you have a dedicated connection to the Internet or you like to check your mail from various locations. You can access your mail using a webbrowser or software such as Outlook or Thunderbird.

POP Account
With this type of email account you only have one folder, the Inbox folder. When you open your mailbox, new mail is moved from the host server and saved on your computer. If you want to be able to see your old mail messages, you have to go back to the computer where you last opened your mail.

With this type of account you do not have to stay logged on to the Internet. You can log on when you want to receive and send new messages. Once your new messages have been downloaded to your computer you can log off to read them. This option is good when you connect with your modem and are charged for your connection or you have an older computer.

Leave mail on server vs. Remove mail from server
If you use the POP3 protocol and you read your mail from multiple computers, you will want to "leave mail on the server." The reason for this is so that the mail in your Inbox will be available to you at all times. If you do not leave mail on the server, all the mail in your Inbox will be downloaded to the computer you are currently using. If you only read your mail from one location, then there is no need to "leave mail on the server." You will see instructions on how to set this option when you go through the steps to set up your email program.

Why choose IMAP rather than POP3 with "leave mail on server"? With POP3 "leave mail on server" only your email messages are on the server, but with IMAP your email folders are also on the server, thus reducing the amount of time required to process your mail. However, because the mail is stored on the server, you may reach your quota frequently. When this happens, new messages cannot be delivered until messages are removed from the server.
