Road Runner E-mail Settings and Outlook

I have a BlackBerry 8530. I also have Road Runner. I have successfully set up my Road Runner account on my BlackBerry. It works great. I can send and receive E-mails with no problems. On my laptop I'm using Microsoft Outlook 2000 for my E-mail client. Yes, I know the program is 10 years old but it does pretty much everything I need so I have no desire to run out and upgrade to the latest version of Office. I'm cheap, what can I say. Anyhow, on my BlackBerry it has "webmail.cfl.rr.com" for the E-mail server. Currently I'm on vacation away from home. I can receive E-mails on my laptop just fine but I can't send E-mails since I'm not connected to my home ISP. Normally the servers I use are pop-server.cfl.rr.com and smtp-server.cfl.rr.com. I've tried using webmail.cfl.rr.com in Outlook 2000 and, of course, it doesn't work. Does anyone have any idea why it doesn't work in Outlook 2000?

Thanks
