ok I really need some help, I have a hotmail, Gmail, yahoo and a basic email account from my isp however, is there some sort of application that will let me join them all together that works in either windows or ubuntu? any suggestions would be grateful :)
Hotmail & possibly Yahoo require you to pay to be able to do this.
An old Application called MrPostman used to allow you to do that. By downloading your e-mails through a java client. Unfortunately, it hasn't been updated in a couple of years. MrPostman - Read your webmail from a pop mail client
Anyway, using MrPostman you could view all of your e-mail from a single program. Such as Outlook Express, Mozilla Thunderbird, or Evolution.
