Post Office Protocol 3 POP3 works by reviewing the inbox on the mail server, and downloading the new messages to your computer. IMAP(Internet Message Access Protocol) downloads the headers of the new messages on the server, then retrieves the message you want to read when you click on it. When using POP3, your mail is stored on your PC. When using IMAP, the mail is stored on the mail server. Unless you copy a message to a "Local Folder" the messages are never copied to your PC. works by reviewing the inbox on the mail server, and downloading the new messages to your computer.

POP3 is Email clients download your emails onto your computer. Using a specialized email program such as Outlook Express or Apple Mail has the advantage of giving you complete control over your email; every email you receive is placed on your computer and you can keep as many large file attachments as you want.

IMAP is protocol that is being used in webmail. Checking your email through our webmail is similar to using Hotmail or YAHOO! Mail. You never actually copy your messages to your computer; in fact, you are looking at them through your web browser on somebody else's computer. When you are not online, you are not able to see your email.

IMAP is a standard protocol for accessing e-mail from a local server. A simpler e-mail protocol is Post Office Protocol 3 (POP3), which downloads mail to the computer and does not maintain the mail on the server.

IMAP, e-mail messages are stored on the server, while in POP3, the messages are transfered to the client's computer when they are read. Thus, using IMAP allows you to access your e-mail from more than one machine, while POP3 does not. This is important because some email servers only work with some protocols.
