Claims to work with : ePrompter automatically and simultaneously checks and retrieves your email messages from up to sixteen password protected email accounts such as AOL, Hotmail, Yahoo, POP3, Earthlink, Juno, MSN, Go .com, Email .com, Mail .com, Mindspring, OneBox, USA.net and hundreds of other email domains .
I used it for ages, cos I was sick of havig OE sit on the taskbar and get in the way. (That was before I found a prog to hide OE to the notification area). Eprompter sits near your clock and will check for emails on a predetermined interval and display a colour-coded ball with the number of messages that are waiting in the specific account.
You can retrieve headers only, delete those you don't want then download into your email client (or even reply directly through eprompter)
