Encrypt Kmail message folder

Has anyone ever tried to encrypt the Kmail "Mail" folder which resides in your home directory. I am not talking about encrypting messages before sending to someone, but rather, all of the plain text messages that you have recieved and sent to people that are on your local machine. I know that you can encrypt an entire partition, but that would be a bit much since the only sensitive data I have is in the Mail folder. I know it is not as simple as using kgpg to encrypt the folder, because Kmail would not be able to unencrypt the folder when trying to read messages.

Thanks, Joel

For this Kmail needs to support GPG operations like on the fly enc/decryption, which AFAIK it doesn't. If you need encryption support you could look into CFS for instance.

If you're attached to Kmail or stuck with it for some reason, then the best thing you could probably do would be to write a script that decrypts the mail folder with GPG, then launches kmail, then re-encrypts it upon exiting kmail.

If you don't want to encrypt the whole filesystem, another option might be to look into a mounted cryptographic image. It's like a crypto filesystem, but doesn't require paritioning. It just runs above your current filesystem. This would be like PGPDrive on the PC. I've heard hdiutil for unix is the way to get the same functionality.

I will look into these suggestions

Thanks for the responding. CFS or TCFS is what I am looking for. Whether it works with Kmail is not critical, I can always change email clients.
Thanks again, Joel
