Own-Mailbox is a personal email server designed to protect your privacy.
Sorry for replying only now, I understand your discontent about us answer only now, but we've been over-busy, and we did not see your message.
1.-Concerning the review of the code we announced that we are going to to have the community be implicated to review the code from day 0. We already have a list of 30 devs willing to do that. We are starting to have a good network including contacts with many security experts including some tor, debian, mozilla and mailpile devs.
We are going to think about having a paid audit by some external company, but it is not always that easy,
2-The fact that Allwinner violates some license does not make any difference to the fact that we don't run any non-free software on it, and that our Board is open-hardware. Unfortunately I don't think there are many big companies that produce processors, that don't do something evil at some point, or that we can give ultimate trust in last resort.
3*. As we mentioned, we will publish security updates regularly. Partnering with a fondation could be a good idea, but 10 000$ is a lot for us, for now.
I enrolled your subscribing list for the improved version of own-mailbox, because I still believe in it. Keep the candle burning guys.
As a potential backer (I have pledged a minimal amount, just to be able to comment, which I feel is fair) I am troubled by the fact that you are pushing to (re-)launch your campaign, yet doing nothing to address the concerns that I (Nickolai Leschov) and PEB raised in the Comments section 6 days ago. It is one thing to disregard the voice of your potential users if you are making money hand over fist, but if you are failing to meet your goals, maybe you should try listening to them?
Before I believe that your product is able to provide better security and privacy than the status quo (email service from a multi-billion-dollar company) and that it is actually open source, I want to have evidence to this end. If you can't be bothered to answer to your potential backers, then I believe I will be be better off with the free offering service from a multi-billion-dollar company and will urge everyone else to do so: at least the established company has much more manpower dedicated to working on the product, is unlikely to stop operating soon and likely to do security right, which is more than can be said about Revolutek so far.
If, on the other hand, you are serious about this project, I suggest you should answer all the comments you are getting in a timely manner (there aren't many).
To sum it up, here are the points that stop me personally from backing this project and heavily recommending it to others:
1. There's no evidence that your product is secure. Without proper security, my email is free from the eyes of service provider, but only until the eyes and hands of the first script kiddie, which is to say that the net benefit of using your product would be negative. I am personally not able to audit the code; you did not answer my question whether any security expert has or will audit it and vouch for your work; and you didn't answer the concerns PEB has raised.
2. You say 'Free Software and Open hardware is important' to you, yet you are using an Allwinner CPU. Allwinner has been notorious for violating GPL license in several ways and unwilling to change. Allwinner is a somewhat popular choice because it's so cheap, but I believe it is not possible to run an open source system on an Allwinner CPU. Maybe you should pick up an alternative? There are several. Again, you did not answer this question.
3*. If there's a vulnerability in the software on these devices, who updates it? Maybe you could improve long-term credibility of your product by partnering with some well-known open-source organization that known to be and will be around for a long time, so that, if you will go out of business, there will be someone else to look at at least some of your code? e.g. OpenBSD Foundation, freeBSD Foundation, etc. I know that in 2015 $10,000 gets you the status of Silver Donor of OpenBSD Foundation; the one that Facebook, Google and Yandex have (that's how underfunded they are).
These are the issues I have with your product so far, that stop me from wholeheartedly funding it, urging others to do so, and maybe even promote it on the internet (I've been doing that to the projects that I especially like).
