15. IMAP in Ruby
By: James Edward Gray II : 2009-03-03
Description: An IMAP client connects to a server, and then authenticates itself using either authenticate() or login(). Having authenticated itself, there is a range of commands available to it. Most work with mailboxes, which may be arranged in an hierarchical namespace, and each of which contains zero or more messages. How this is implemented on the server is implementation-dependent; on a UNIX server, it will frequently be implemented as a files in mailbox format within a hierarchy of directories.
