All three are different ways of handling a remote mailbox, but you proably know that already... POP3 - simple protocol, all your mail is delieverd to a remote mailbox, your pop client copies it to your local system (it may or may not be deleted from the mailbox host). Advantages, simple, widely supported by clients both text & GUI on a variety of platforms. Disadvantages, simple, no remote mailbox management, loss of delivery info (useful when tracing the origin of a message, e.g. spam). IMAP - more of a remote mailbox management protocol. Allows you to delete or move messages between mailboxes in place, i.e. on the remote server. Because your mail stays in place you can access your mailbox from multiple clients, potentially from different sites. Advantages, better management of remote mailbox, controlled download of attachments, folder management. Disadvantges, the protocols a bit clunky though this can be hidden by a good client. Web mail - generally a bunch of cgi scripts that give you access to a remote mailbox, e.g. Hotmail et al. Facilities depend on what the developer decided to write in at the time. Whilst there is no standard protocol as such, because the interface is Web based it can be accessed from just about anything, usual stuff + Palm Pilots, Psion, Lynx text browser........ Which is best ? Depends on what you want. - For maximum accessibility probably web based, particularly if its a public server. HTTP pass through is probably the most common feature of firewalls, again adding to accessibility. -For functionality/accessibility IMAP. Although if you only ever intend to use one client system you probably won't notice much difference between POP & IMAP. -If your mailbox is on a service providers system you may have space limitation or extra charges imposed if your mailbox grows too large. This will impact IMAP & Web based.
