This customized version of the Thunderbird mail program lets you take your mail settings and mailboxes with you.

Maintaining a single e-mail message repository whether online or off, at home or at large, requires a portable e-mail application. Like Firefox Portable as I featured here before, Thunderbird Portable lets you take your e-mail program with you on a USB drive wherever you go, just plug into a Windows PC.
