IMAP vs. POP email protocol

U. of London Computing Services has chart comparing IMAP with POP. IMAP would seem better for those who access mail from multiple computers, since client and server directory structure are kept in synch. Note that Eurdora-->Options-->Incoming Mail requires "IMAP Mailbox Location Prefix". Check Email FAQs from Medical ITS. Also see document: Eudora Setting for Yale, the latter says to leave IMAP Mailbox Location blank. Also "Minimal" for downloading new mail; "Mark it deleted" for deleting messages; and "Passwords (or Kerberos)" for Authentication style.
