An alternative protocol is Internet Message Access Protocol (IMAP). IMAP provides the user with more capabilities for
retaining e-mail on the server and for organizing it in folders on the server. IMAP can be thought of as a remote file server.
POP and IMAP deal with the receiving of e-mail and are not to be confused with the Simple Mail Transfer Protocol (SMTP).
You send e-mail with SMTP, and a mail handler receives it on your recipient's behalf. Then the mail is read using POP or
IMAP. IMAP4 and POP3 are the two most prevalent Internet standard protocols for e-mail retrieval. Virtually all modern
e-mail clients and servers support both.
