Reply To: IMAP vs POP3
It was my understanding that IMAP is a superset of POP, so it should also be possible to keep a local copy of the messages when using IMAP.
With POP there’s also usually an option to “delete messages from the server after x days.”. I use POP with that option on my main desktop and set the other computers up with IMAP.
One advantage of IMAP is that other folders such as Sent, Drafts, and any others you create, will be synced between computers. With POP, if you wanted to look at your sent mail, you’d have to look at the exact computer and program you sent it from. That to me is the biggest argument in favor of IMAP. Of course you could always Cc yourself when sending mail.
