Regular POP or IMAP e-mail
Your device can download e-mails from a POP or IMAP e-mail
account.
POP3 is a version of the post office protocol that is used to
store and retrieve e-mail or internet mail messages from a
server. IMAP4 is a version of the internet message access
protocol that lets you access and manage e-mail messages
while the messages are still on the e-mail server. You can then
choose which messages to download to your device.
