POP or IMAP?

I love IMAP because I access Gmail from my Mac and my iPod Touch, and IMAP keeps them in sync. Messages deleted on one disappear on the other.

POP3 if you only use 1 device to check the account.
IMAP if you check the account from multiple devices as it makes it easier to keep track of things.

There is a good article here:

IMAP is a newer protocol than POP, in that it allows for interaction with the servers, like you have with the browser-based gmail interface. POP just opens a connection with the server, downloads your mail, and closes down again, but IMAP can deliver new messages to your inbox as they arrive.

IMAP for sure. It is much more convenient to have the same set of email on every client as well as on the web.I switched over a year or so ago and have not looked back.

I prefer IMAP over POP, but have had weird issues with the Mail.app (os x), gmail, and my blackberry. Because Mail saves a draft every now and then, the draft gets sent to my blackberry, which can be bothersome at times.

Thanks everyone – I’m going to look in to swapping over to IMAP tonight!

if you are not always-connected to the internet POP3 otherwise IMAP4
