IMAP over POP
Lifehacker links up an article by Macworld writer Jenifer Berger on switching from POP to IMAP -
Why IMAP is better than POP
Macworld writer Jennifer Berger switched from POP to the IMAP protocol to retrieve her email from several different computers and she isn’t looking back:
POP (Post Office Protocol) mail downloads your mail to your hard drive, while IMAP (Internet Message Access Protocol) keeps everything—even your sent mail—on a server. In short, IMAP gets you e-mail portability without having to use a Web-based e-mail interface. And theoretically, any e-mail address can support POP or IMAP—the administrator or Internet service provider (ISP) just has to support IMAP.
I only use one computer. My notebook is my computer at the office, on the road, at home and away on holidays. So, I have moved a way from IMAP as I don’t see the need but if you use your mail at more than one computer I can see the significant advantages.
