IMAP stands for the Internet Message Access Protocol. It enables a mail client (such as Thunderbird) to access messages stored on a mail server. It is more modern and fully featured than POP (Post Office Protocol), which is the other major protocol for accessing mail messages. Most email providers now support IMAP. To see whether your account uses IMAP or POP, check the Server Settings page in the Account Settings.
