Own-Mailbox, confidential and opensource mailbox

own-mailbox logoToday I’d like to present Own-Mailbox, a french project currently on kickstarter.

Their objective is to provide a 100% confidential AND opensouce solution for emails.

Own-Mailbox is a tiny email server (Smaller than a Raspberry PI) based on open hardware and opensource software to protect your personal emails. You simply need a power source + an ethernet connection and Own-Mailbox will do the rest. (Configure your access, your domain, etc…)

Based on Debian, and running with Postfix and Roundcube (Webmail), the team have directly integrated GPG (for the encryption of your emails). The main strength but issue at the same time with GPG is that the reader of your mail needs also to have a GPG key to read your mail. If you send an email to a non GPG friend, well, GPG is then useless.

To solve this issue, Own-Mailbox is providing a temporary and filtered HTTPS connections to read the email directly on the server (Based on the Private Link Message method)

Obviously Own-Mailbox have others features, such as easy access to log, private folder, etc…

As you might ask, why did they not use the Raspberry PI? Pretty simple, the R.PI is not open-hardware (For example, the processor is closed-source and even the spec sheet is not accessible to public) and also requires non-free drivers to work. Also, the size and the power consumption does not fit their requirement. Last but not the least, the total cost if using Raspberry PI (Including SD card, Power supply, case, …) would have cost more.

The team is looking to raise 95,000 EUR. In couples of days, they already raised more than 40,000 EUR, mainly through early bird purchase. There is no doubt that they will successfully raise the needed amount.

It does look like a very robust project (I’ve even backed them up!).

You can have a look to their website or directly on their kickstarter page to get more information.

  1. hi,

    lokks nice.

    But they fail to run a proper configured webserver. check their tests. it’s devastating.

    There is no single line about their used hardware setup. (i am not counting FAQ)

    256mb is too low, if you want to run spamassasin or similar spam prevention software.

    the mailserver is not capable of STARTTLS. Thats for me the dealbreaker. They are building some kind of security related mail stuff box something and they even show basic security fails and misconfiguration on their own mailbox.

    their homepage is shiny.
    the hardware looks nice.


    1. Well it seems the project did not fly…and they did not collect sufficient funds.
      But they got a lot of information from the community (Some of your points have been explicitly shared as I can see).

      Let’s hope they can improve it and have successful campaign.

      I will be glad not to worry about my emails if they could do it properly 🙂

  2. but i have a new thing to be featured on your blog:

    its already funded – CHECK
    there are already 2000 devices out on the road – CHECK
    its not the PRE-Prototype, its the second or third hardware revision of the board.
    its open hardware and newly self designed (not like anonabox or own-mail with some prebuilt stuff)
    its a NGO – Mix out of Czech Repulic and

    and for mail stuff, please do a tutorial for
    it looks lightweight. the used software isnt’ but the suite to keep the stuff together is.
