prepop is a simple "online" POP3 email client, very suitable for dialups and other slow connections. It lets you read the text/plain part of your email messages without having to download those big pesky attachments (over dialups this can sometimes take a long time and during this time you often have no idea on how much data is left to be transferred). With prepop you can also see the size of all the messages when listing them. You can't reply to messages since this was not what prepop was designed to do. prepop was not designed to be an alternative to your current email client. It's more of a complementing email client doing some of the things your ordinary email client should have handled in the first place.
