Dmail

To me, Delicious does not have a long history of reliable software. So there's some trepidation around my intrigue to their latest offering - Dmail, the self-destructing email tool. The concept is solid - send an email with sensitive information and after a predetermined amount of time, the information becomes scrambled and useless. How this actually works is a bit beyond me as I don't see how any service can alter the contents of an email sent through Gmail but I guess that magic is what the offering really is. It's also not clear if the recipient needs to have the Dmail plugin installed as well and, if so, why anyone would do that instead of just keeping your sensitive info?

So, yea, interesting concept but I have questions!
