The Difference between viewing mail with a POP3 server and with a IMAP server

• What viewing e-mail with a POP3 server does: When using a POP3 server, when you open your e-mail client and access your mail as a default all your mail is sent to your computer from the post box on your mail server. So all the mail you see is on your computer.

• What viewing e-mail with a IMAP server does: When using a IMAP server, when you open your e-mail client and access your mail none of the mail is sent to your computer. The mail you see is still in the post box of the mail service provider you have. The mail is not brought to your computer.
