IMAP (143-993)

Internet Message Access Protocol.

Protocol Information

IMAP is a protocol used to access email directly from the server, without having to download it. This allows users to synchronize their mail across multiple devices, so that any changes made on one, such as reading or deleting a message, are also visible on the others. IMAP is ideal for those who use multiple devices to manage their email, as all operations take place in real time on the server, keeping a copy of each email accessible from anywhere with an Internet connection. It also supports folder structures.
