You can't cancel a message. Once it's left your inbox, it's gone. And Google won't/can't do anything (unless the recipient is gmail) because just as it will have gone from your outbox, it will have gone from their system before you've even realised "oh shit I didn't mean to hit send". You're effectively relying on the recipient's mail client to honour a request to throw the previous message away, and many clients either don't honour, or don't even recognise, such a request. That's why a previous mail client of mine (Turnpike), by default, wouldn't empty the outbox until the contents were at least a minute old. Cheers, Wol
