IMAP EMAIL Frequently Asked Questions: What is IMAP?
IMAP stands for “Internet Message Access Protocol” – and is an email service which helps accessing your mailbox from different computers and locations. The mail is actually held on the server, rather than downloaded to your PC. This is great news if you have a computer problem and have to re-install your operating system from scratch, because your important mail will always be server side and no email loss will occur.
