IMAP

IMAP is short for Internet Message Access Protocol, which is a pretty good way to quickly describe what it is!

IMAP is a mechanism through which you may connect to and access your email from a remote system – often an email client.

Offering clever things like folder synchronisation, IMAP offers some advantages over the less flexible POP3 connection, particularly if you’d like different mail systems to look the same (your remote and your local mailbox, for example).
