GeeMail desktop client for Gmail provides offline access

GeeMail is a desktop client for Gmail based on Adobe AIR. In other words, it can run on Windows, Linux, or OS X as long as you have Adobe AIR installed. At its most basic level, GeeMail is a standalone application that you can use to check your email, send, or sort messages without opening a web browser.

But GeeMail also supports offline Gmail access. In other words, you can compose messages while you're away from an internet connection. When you go online again, GeeMail will send them. Google also provides limited offline support to users who install Google Gears.

GeeMail lacks a search box, which is a bit limiting. But what it does provide is super-fast access to your Gmail inxbox.
