This is a superb GMail Backup Utility made with FLASH+PHP+XML.
I created this for me to take backups of tonnes of my mails at GMail. I do not trust any third party application for taking backups. Today, I thought that it will be good if I could help someone. The script contains no spyware. Trust me. :)

This is very helpful to the users who have slow internet speed.

How to Use:
Just extract the zip file attached and upload it to your server. Feed the username and password and you will get the list of all the folders available in your account. The login information is not saved anywhere on your server so you will have to feed it every time you open the application, just for perfect security. Select the folders you want to backup and the mails will come to your server.

The application is very much user-friendly. It guides you for everything with the information alerts.

For more security... upload the application at an unknown folder on your server. Take backup. Will be done within minutes. Then... change the permissions of your folder to 000. So that, no one can access it even if he/she gets to know the path to your backup folder.

You can then zip the e-mails using the tools given by your hosting provider and download the zip file to your computer. Make sure that you download the zip file via SFTP instead of just FTP. SFTP is 100% secure and no one can hack the connection between your computer and your server.

For more security... users who have fast internet speed, may install it on their localhost server on their computer... so that they will get the e-mails directly on their computer.

The e-mails are stored in a backup folder as .eml format. So, you can open them easily using any software like Outlook. The attachments to the e-mails are also included in the same .eml file.

The connection to your mailbox is set using IMAP. You can backup e-mails from other services too instead of just GMail. What you need to do is just change the IMAP server URL in the query.php file.
For example for GMail it is...
{imap.gmail.com:993/imap/ssl/novalidate-cert}

Enjoy!!!
