Explanation of IMAP E-mail Accounts

IMAP (Internet Message Access Protocol) is an advanced protocol for receiving e-mail. It is a method of accessing e-mail messages which are stored on a mail server. 1&1 suggests using IMAP over POP3 with some explanation below.

The main advantage of IMAP over POP3 is the ability to keep the original e-mail stored on the mail server and the ability to access the same account from multiple locations. Unlike POP3 where e-mail is downloaded to the computer or device checking for mail and completely removed from the mail server, IMAP simply downloads a copy of the e-mail. This is much more convenient as the e-mail account can be set up on multiple computers and devices using IMAP and the original e-mail will always remain on the mail server.

In cases where a mobile phone or personal computer was configured to be the primary means of checking e-mail and malfunctions, is lost, stolen, or totally inoperable, the e-mails will not be lost. Set up the account using IMAP on another computer, device or simply check the 1&1 Webmail at http://email.1and1.com/ and find that all e-mails are still intact!
