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.

I am trying to:
2014-08-23 22:09:07 +00:00
* Make deploying a good mail server easy.
* Promote [decentralization ](http://redecentralize.org/ ), innovation, and privacy on the web.
2014-05-15 12:57:38 +00:00
* Have automated, auditable, and [idempotent ](http://sharknet.us/2014/02/01/automated-configuration-management-challenges-with-idempotency/ ) configuration.
2015-05-19 15:18:53 +00:00
* **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
-------
2015-05-22 20:53:13 +00:00
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.
2015-08-14 21:04:42 +00:00
It is a one-click email appliance. There are no user-configurable setup options. It "just works".
2015-05-22 20:53:13 +00:00
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
2015-08-17 12:20:31 +00:00
* Backups ([duplicity](http://duplicity.nongnu.org/)), firewall ([ufw](https://launchpad.net/ufw)), intrusion protection ([fail2ban](http://www.fail2ban.org/wiki/index.php/Main_Page)), system monitoring ([munin](http://munin-monitoring.org/))
2015-06-03 20:30:26 +00:00
It also includes:
2015-06-06 12:55:13 +00:00
* A control panel and API for adding/removing mail users, aliases, custom DNS records, etc. and detailed system monitoring.
2015-08-17 12:20:31 +00:00
* Our own builds of postgrey (adding better whitelisting) and dovecot-lucene (faster search for mail) distributed via the [Mail-in-a-Box PPA ](https://launchpad.net/~mail-in-a-box/+archive/ubuntu/ppa ) on Launchpad.

For experts, start with a completely fresh (really, I mean it) Ubuntu 14.04 LTS 64-bit machine. On the machine...

v0.14
v0.14 (November 4, 2015)
------------------------
Mail:
* Spamassassin's network-based tests (Pyzor, others) and DKIM tests are now enabled. (Pyzor had always been installed but was not active due to a misconfiguration.)
* Moving spam out of the Spam folder and into Trash would incorrectly train Spamassassin that those messages were not spam.
* Automatically create the Sent and Archive folders for new users.
* The HTML5_Notifier plugin for Roundcube is now included, which when turned on in Roundcube settings provides desktop notifications for new mail.
* The Exchange/ActiveSync backend Z-Push has been updated to fix a problem with CC'd emails not being sent to the CC recipients.
Calender/Contacts:
* CalDAV/CardDAV and Exchange/ActiveSync for calendar/contacts wasn't working in some network configurations.
Web:
* When a new domain is added to the box, rather than applying a new self-signed certificate for that domain, the SSL certificate for the box's primary hostname will be used instead.
* If a custom DNS record is set on a domain or 'www'+domain, web would not be served for that domain. If the custom DNS record is just the box's IP address, that's a configuration mistake, but allow it and let web continue to be served.
* Accommodate really long domain names by increasing an nginx setting.
Control panel:
* Added an option to check for new Mail-in-a-Box versions within status checks. It is off by default so that boxes don't "phone home" without permission.
* Added a random password generator on the users page to simplify creating new accounts.
* When S3 backup credentials are set, the credentials are now no longer ever sent back from the box to the client, for better security.
* Fixed the jumpiness when a modal is displayed.
* Focus is put into the login form fields when the login form is displayed.
* Status checks now include a warning if a custom DNS record has been set on a domain that would normally serve web and as a result that domain no longer is serving web.
* Status checks now check that secondary nameservers, if specified, are actually serving the domains.
* Some errors in the control panel when there is invalid data in the database or an improperly named archived user account have been suppressed.
* Added subresource integrity attributes to all remotely-sourced resources (i.e. via CDNs) to guard against CDNs being used as an attack vector.
System:
* Tweaks to fail2ban settings.
* Fixed a spurrious warning while installing munin.

* 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 ).
2015-05-22 20:53:13 +00:00
* 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.
2014-06-10 22:48:09 +00:00
* 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.
