Multiple E-mail access from single webpage

Hi, I am looking for a script or webpage that gets all my e-mail from multiple accounts like (a)yahoo (b)google (c)netzero and dump/store in a single page. So if i logon to that page i would be able to see all my mail. I also want the functionality of all the e-mails from above mails to be forwarded to a single e-mail. Plesae get back to me if you need more details
