Webmail is a web-based mail client. It is well suited for users who must access their mail without having software other than a web browser, a situation travelers often face. Webmail is specifically useful if you are using a computer that you can not configure to view your mail account. In addition to reading and sending mail, Webmail allows you to filter messages and save messages into different folders on your mail account. Webmail also displays your mail quota use.
