What are POP3 and IMAP e-mail accounts?


POP3 (Post Office Protocol) and IMAP (Internet Message Access Protocol) are methods
used by your computer to access e-mail messages from a remote server. 1&1 e-mail
accounts are compatible with both POP3 and IMAP.

E-mail stored on an IMAP server can be manipulated using an e-mail client (such as
Microsoft Outlook) from different computers without the need to transfer messages or
files back and forth between the computers. This is possible because the messages
are stored on the server, unlike POP3, where messages must be downloaded to a local
system.

A strong advantage of IMAP is that it allows users to set up IMAP folders on the server.
Incoming mail can then be organized into the correct folder. This is especially helpful if
the IMAP e-mail account is shared by more than one user.


Please note: It is not possible to set up automatic filter rules on the
server. This means you have to use your e-mail client to sort your e-mail.
