Mail-in-a-Box

Mail-in-a-Box helps individuals take back control of their email by defining a one-click, easy-to-deploy SMTP+everything else server: a mail server in a box.
|
|
|
|
**Please see [https://mailinabox.email](https://mailinabox.email) for the project's website and setup guide!**

I am trying to:
|
|
|
|
* Make deploying a good mail server easy.
|
|
* Promote [decentralization](http://redecentralize.org/), innovation, and privacy on the web.
|
|
* Have automated, auditable, and [idempotent](http://sharknet.us/2014/02/01/automated-configuration-management-challenges-with-idempotency/) configuration.
|
|
* **Not** make a totally unhackable, NSA-proof server.
|
|
* **Not** make something customizable by power users.
|
|
|
|
This setup is what has been powering my own personal email since September 2013.

|
|
The Box
|
|
-------
|
|
|
|
Mail-in-a-Box turns a fresh Ubuntu 14.04 LTS 64-bit machine into a working mail server by installing and configuring various components.
|
|
|
|
It is a one-click email appliance (see the [setup guide](https://mailinabox.email/guide.html)). There are no user-configurable setup options. It "just works".
|
|
|
|
The components installed are:
|
|
|
|
* SMTP ([postfix](http://www.postfix.org/)), IMAP ([dovecot](http://dovecot.org/)), CardDAV/CalDAV ([ownCloud](http://owncloud.org/)), Exchange ActiveSync ([z-push](https://github.com/fmbiete/Z-Push-contrib))
|
|
* Webmail ([Roundcube](http://roundcube.net/)), static website hosting ([nginx](http://nginx.org/))
|
|
* Spam filtering ([spamassassin](https://spamassassin.apache.org/)), greylisting ([postgrey](http://postgrey.schweikert.ch/))
|
|
* DNS ([nsd4](http://www.nlnetlabs.nl/projects/nsd/)) with [SPF](https://en.wikipedia.org/wiki/Sender_Policy_Framework), DKIM ([OpenDKIM](http://www.opendkim.org/)), [DMARC](https://en.wikipedia.org/wiki/DMARC), [DNSSEC](https://en.wikipedia.org/wiki/DNSSEC), [DANE TLSA](https://en.wikipedia.org/wiki/DNS-based_Authentication_of_Named_Entities), and [SSHFP](https://tools.ietf.org/html/rfc4255) records automatically set
|
|
* Firewall ([ufw](https://launchpad.net/ufw)), intrusion protection ([fail2ban](http://www.fail2ban.org/wiki/index.php/Main_Page))
|
|
* A control panel and API for adding/removing mail users, aliases, custom DNS records, etc. and system monitoring.

|
The Security
|
|
------------
|
|
|
|
See the [security guide](security.md) for more information about the box's security configuration (TLS, password storage, etc).
|
|
|
|
I sign the release tags on git. To verify that a tag is signed by me, you can perform the following steps:
|
|
|
|
# Download my PGP key.
|
|
$ curl -s https://keybase.io/joshdata/key.asc | gpg --import
|
|
gpg: key C10BDD81: public key "Joshua Tauberer <jt@occams.info>" imported
|
|
|
|
# Clone this repository.
|
|
$ git clone https://github.com/mail-in-a-box/mailinabox
|
|
$ cd mailinabox
|
|
|
|
# Verify the tag.
|
|
$ git verify-tag v0.08
|
|
gpg: Signature made ..... using RSA key ID C10BDD81
|
|
gpg: Good signature from "Joshua Tauberer <jt@occams.info>"
|
|
gpg: WARNING: This key is not certified with a trusted signature!
|
|
gpg: There is no indication that the signature belongs to the owner.
|
|
Primary key fingerprint: 5F4C 0E73 13CC D744 693B 2AEA B920 41F4 C10B DD81
|
|
|
|
The key ID and fingerprint above should match my [Keybase.io key](https://keybase.io/joshdata) and the fingerprint I publish on [my homepage](https://razor.occams.info/).

Mail-in-a-Box is similar to [iRedMail](http://www.iredmail.org/) and [Modoboa](https://github.com/tonioo/modoboa).

The History
|
|
-----------
|
|
|
|
* In 2007 I wrote a relatively popular Mozilla Thunderbird extension that added client-side SPF and DKIM checks to mail to warn users about possible phishing: [add-on page](https://addons.mozilla.org/en-us/thunderbird/addon/sender-verification-anti-phish/), [source](https://github.com/JoshData/thunderbird-spf).
|
|
* In August 2013 I began Mail-in-a-Box by combining my own mail server configuration with the setup in ["NSA-proof your email in 2 hours"](http://sealedabstract.com/code/nsa-proof-your-e-mail-in-2-hours/) and making the setup steps reproducible with bash scripts.
|
|
* Mail-in-a-Box was a semifinalist in the 2014 [Knight News Challenge](https://www.newschallenge.org/challenge/2014/submissions/mail-in-a-box), but it was not selected as a winner.
|
|
* Mail-in-a-Box hit the front page of Hacker News in [April](https://news.ycombinator.com/item?id=7634514) 2014, [September](https://news.ycombinator.com/item?id=8276171) 2014, and [May](https://news.ycombinator.com/item?id=9624267) 2015.
