10.7.What is the difference between POP3 and IMAP ?

The Difference

POP3 works by reviewing the inbox on the mail server, and downloading the new messages to your computer. IMAP 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.

Scenarios of Use

POP3

· You only check e-mail from one computer.

· You want to remove your e-mail from the mail server.

IMAP

· You check e-mail from multiple locations.

· You use Webmail.
