What is POP3

Post Office Protocol 3 (POP3) is the most recent version of a standard protocol for receiving e-mail. POP3 allows you to download email messages on your local computer and read them even when you are offline. POP3 makes it easy for anyone to check their email from any computer in the world, provided they have configured their email program properly to work with the protocol.

What is IMAP

IMAP (The Internet Message Access Protocol) is a mail protocol used for accessing email on a remote web server from a local client. IMAP provides the user more capabilities for retaining e-mail on the server and for organizing it in folders on the server. Compared to POP3, IMAP allows users to log into many different email clients or webmail interfaces and view the same emails, because the emails are kept on remote email servers until the user deletes them.
