TASK 1.21

Find out the differances between IMAP4 and POP3. Write a brief description of how each protocol works.

USING INBOX TO GET E-MAIL

Each time you get your e-mail using Inbox, you are using an Internet standard protocol to retrieve your e-mail from the mail server. This protocol defines the Inbox features and capabilities, and how you interact with your mail server. The Pocket PC supports both POP3 (Post Office Protocol version 3) and IMAP4 (Internet Message Access Protocol version 4) protocols for retrieving e-mail. Once you dial your ISP or corporate network to access e-mail, these protocols facilitate the download. Let's look at what POP3 and IMAP4.


WHAT IS IMAP4 PROTOCOL?

The IMAP4 protocol provides the ability to download e-mail messages to your Pocket PC. You can control whether e-mail messages are synchronized with your mail server. You can choose to store e-mail in separate folders, and you can select whether or not to synchronize a specific folder. You can even, if you wish, download mail one message at a time.


WHAT IS POP3 PROTOCOL?

The POP3 protocol provides the ability to download e-mail messages to your Pocket PC. You can control whether the whole message is downloaded, or whether the messages are then deleted off your e-mail server. You can compose messages offline and send them. However, you cannot synchronize your e-mail directly with your mail server. In addition, POP3 does not support multiple folders for e-mail. All e-mail is received in the same folder.
