Definition of Terms:

POP — Post Office Protocol (POP) is a standard protocol for accessing email. Email accessed using a program (or client) that supports POP will be downloaded to your computer and no longer maintained on the server. If you only check your email from one computer (i.e. laptop), and need the ability to work offline, you might want to consider using a POP supported program like Outlook Express, Netscape Communicator or Eudora Light. (The full Outlook client also provides the ability to work offline.)

IMAP — Interactive Mail Access Protocol (IMAP) is a standard protocol for accessing email. Email stored on an IMAP server can be accessed from a computer at home, a computer at the office, and a laptop computer while traveling, without the need to transfer messages or files back and forth between these computers. If you need to access your email from more than one computer, ICT highly recommends using IMAP. Programs that support IMAP include Outlook Express, Netscape Messenger, and Eudora Pro. IMAP requires a constant connection to the email server while you are accessing your email. If you are interested in learning more technical details about IMAP go to
