LemonMail just released the testnet version of Mail, and it's looking pretty slick!
Welcome to Lemon Mail DApp!
Hi,
We just wanted to drop you a quick message to demonstrate how this decentralized application works.
This email was sent to you by uploading it's content to IPFS, a peer-to-peer storage network, and then storing the IPFS hash on the Ethereum blockchain, a distributed transaction ledger. The Javascript code running within your browser has then recognized this blockchain transaction and pulled the corresponding content from IPFS.
In other words, no centralized back-end was needed in order to deliver this message to you! You can view both encrypted IPFS content and Ethereum transaction by following the links above.
You can send mails to "normal" servers, obviously you lose the decentralized part
it's a pretty cool idea, and I hope they will offer this service on the main net soon!
