What is IMAP?

  1. IMAP stands for Internet Message Access Protocol. (the latest version is IMAP Version 4)
  2. IMAP allows you to always work with your mail live on the server.
  3. You can view just the heading and the sender of the letter and then decide whether to download the mail which will save your time.
  4. You can also create and manipulate multiple folders or mailboxes on the server, delete messages, or search for certain parts or an entire note.
  5. IMAP requires continual access to the server during the time that you are working with your mail. This means that you must be connected to the Internet at all times, to send / receive.
  6. IMAP is faster than POP because the mail client reads all of the message headers without having to download the entire message.
  7. IMAP is used in Microsoft Outlook, Thunderbird, Blackberry, Gmail, iPhone.

Advantages over POP:

  1. The POP protocol requires only one client to be connected to the mailbox but the IMAP protocol allows simultaneous access by multiple clients.
  2. IMAP clients can create, rename, and/or delete mailboxes on the server and can use Multiple mailboxes on the server.
  3. IMAP provides a mechanism for a client to ask the server to search for specific messages which avoids requiring clients to download every message in the mailbox.
  4. POP downloads all emails into 1 mail folder called “Inbox” whereas IMAP preserves your folder structure in a main folder just as you have setup on the server.
