What is the difference between the POP and IMAP mail protocols and which one should I be using?
Basically, IMAP works by keeping mail on the server and POP works by downloading mail to your computer. If you usually use the POP protocol to check mail, then when you use the webmail interface you will only have access to new mail (the Inbox folder) – none of the folders you created in your e-mail application will be available. Likewise, if you create folders via webmail, those folders will not be available the next time you check your mail via your e-mail application If you normally use IMAP to check your mail, all of your folders will be accessible using the Horde webmail interface (SquirrelMail does not support IMAP). Heres a comparison of the IMAP and POP protocols. If you configure your e-mail client application to use IMAP, you should choose Horde when you access webmail.
