When they click it, they’ll be redirected to Dmail’s website, which is how they give you such complete control over who can view your messages and when. Wouldn’t it be nice to have something like that for email, too?

The interesting and smart thing about Dmail is that when you send a mail secured through Dmail, once the mail is received it appears saying “This secure message was sent using Dmail”. It’s for those emails with important messages that won’t be saved later and won’t be turned up by a hacker and submitted to the public, similar to what recently happened with Sony. Even Dmail users can keep a self-destruct time to every email – like in an hour, a day, a week or never. They’re also working on premium features, one of which will be the ability to send self-destructing attachments in your emails… like blueprints of your nemesis’ secret volcano lair or the schematics of his latest insidious weapon.
Dmail takes the concept of Google’s current un-send feature a step farther.
If you don’t have a predetermined time frame, pick “never” as your time frame. Once the message self-destructs, recipients get a message that the email is no longer available when they try to read it.
Dmail presently works only with Gmail, the long-term goal is to expand access to other platforms, including Google Apps.
Although you can receive Dmail messages from any email account or client, you can only send them through Gmail on Chrome. Neither Gmail nor Dmail servers ever receive both the decryption key and encrypted message.

If the sender doesn’t cancel during their email grace period, the message will be sent to the recipient as soon as the delay expires. “Only the recipient and sender can read the email legibly”, said lead on the Dmail project, Eric Kuhn.
