Internet Message Access Protocol (IMAP) commands are much more complicated than POP3. Some examples:

• Login User - prefix LOGIN user pass
• Lost Folders - prefix LIST "" "\*"
• List Emails in INBOX - prefix EXAMINE INBOX
• Close Connection - prefix LOGOUT

Here prefix is a random prefix we provide to track server replies to various commands. IMAP accepts a lot of different user authentication methods; LOGIN is just the simplest (and least secure).
