What is GWFTB? Do you need to move your emails from Thunderbird and/or mbox-client to Gmail/Google Apps? Are you using Thunderbird IMAP to manage your Gmail/Google Apps account, yet always failing to sync your emails? Do you have an endless hierarchy of folders on Thunderbird that you wish to also see on your Gmail/Google Apps account? Do you need to upload those old emails from the 90's to your Gmail/Google Apps account, with correct dates and readable content? If any of the above describes your needs, then GWFTB was made for you. Migration to Gmail/Google Apps has never been easier. GWFTB stands for Google webMail Filer For Thunderbird. GWFTB started as a GPL/Free program and gained fame and publicity as a free software, but development on the free version was discontinued, yet GWFTB is offered for a next-to-free price!
