the author of this app says:
If you need a simple, no-fuss e-mail client, this may be for you. This application sends e-mail without the overhead of some of the more powerful e-mail clients available for the PalmOS platform.
The real simplicity and ease of use comes from its ability to quickly look up e-mail addresses from AddressBook or change your e-mail server with just one tap. There's no need to navigate multiple screens and preference options.
Color or grayscale PalmOS devices supported.
