You may have noticed there are two method (POP3 and IMAP) for accessing your email inbox and maybe wondering what is the difference between them, here is a brief explanation :-
Post Office Protocol version 3 (POP3) is the standard protocol most commonly used for email client to communicate with mail server for retrieving email messages in inboxes. Email clients setup to use this protocol to access email inboxes will automatically download all messages found in the inbox to the email client's mail folders. This allow you to browse through them in offline sessions.
Internet Message Access Protocol (IMAP) is gaining popularity when there is a growing need to keep email messages off the email client and kept in the server side. This access method does not download the email messages in the inboxes, it merely grep a list of email message headers to show in the email client, users are required to manually clear the messages in the inboxes as and when needed to free up web space in web hosting account, if the messages are kept too long ad the total web space usage has exceeded quota set, new messages may not be able to be saved in the inbox and mail server will bounce them back to sender after several fail attempts to save. This method of accessing inboxes is suitable for multiple user managing one inbox, keeping the messages at server side allow every member given access to the inbox has a chance to read all email messages.
