Mail-in-a-Box with Quotas

This is an experimental implementation of Mail-in-a-box with quota support.

Quotas can be set and viewed in the control panel

To set quotas from the command line, use:

tools/mail.py user quota <email> <quota>

To set the system default quota for new users, use:

tools/mail.py system default-quota <quota>

Mailbox size recalculation by Dovecot can be forced using the command:

doveadm quota recalc -A

Please report any bugs on github.

Installing v0.4x-quota

To install the latest version, log into your box and execute the following commands:

$ git clone https://github.com/jrsupplee/mailinabox.git
$ cd mailinabox
$ sudo bash setup/bootstrap.sh

Follow the standard directions for setting up an MiaB installation. There are no special installation steps for installing this version.

The default quota is set to 0 which means unlimited. If you want to set a different default quota, follow the directions above.

Upgrading v0.4x to v.0.4x-quota

This is experimental software. You have been warned.

Rename your mailinabox directory to something like miab.old
Clone this repository using:

git clone https://github.com/jrsupplee/mailinabox.git
cd into mailinabox and run sudo bash setup/bootstrap.sh On occasion there are lock errors when updating Munin. Just re-run sudo setup/start.sh until the error does not occur.
Note: all existing users at the time of the upgrade will have there quota set to 0 (unlimited).

Upgrading MiaB with quotas to a New Version

cd into the mailinabox directory.
Execute git pull to download the latest changes.
Execute sudo bash setup/bootstrap.sh to checkout the latest version and re-run setup.

Issues

When a user's quota is changed, any IMAP session running for that user will not recognize the new quota. To solve this a dovecot reload could be issued causing all current IMAP sessions to be terminated. On a system with many users, it might not be desirable to reset all users sessions to fix the quota for one user. Also if the administrator is setting the quota for several users it would result in the continual reset of those connections.

Mail-in-a-Box
=============

By [@JoshData](https://github.com/JoshData) and [contributors](https://github.com/mail-in-a-box/mailinabox/graphs/contributors).

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!**

* * *

Our goals are to:

* Make deploying a good mail server easy.
* Promote [decentralization](http://redecentralize.org/), innovation, and privacy on the web.
* Have automated, auditable, and [idempotent](https://web.archive.org/web/20190518072631/https://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.

Additionally, this project has a [Code of Conduct](CODE_OF_CONDUCT.md), which supersedes the goals above. Please review it when joining our community.


In The Box
----------

Mail-in-a-Box turns a fresh Ubuntu 18.04 LTS 64-bit machine into a working mail server by installing and configuring various components.

It is a one-click email appliance. 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 ([Nextcloud](https://nextcloud.com/)), and Exchange ActiveSync ([z-push](http://z-push.org/)) servers
* Webmail ([Roundcube](http://roundcube.net/)), mail filter rules (thanks to Roundcube and Dovecot), and email client autoconfig settings (served by [nginx](http://nginx.org/))
* Spam filtering ([spamassassin](https://spamassassin.apache.org/)) and greylisting ([postgrey](http://postgrey.schweikert.ch/))
* DNS ([nsd4](https://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), [MTA-STS](https://tools.ietf.org/html/rfc8461), and [SSHFP](https://tools.ietf.org/html/rfc4255) policy records automatically set
* TLS certificates are automatically provisioned using [Let's Encrypt](https://letsencrypt.org/) for protecting https and all of the other services on the box
* Backups ([duplicity](http://duplicity.nongnu.org/)), firewall ([ufw](https://launchpad.net/ufw)), intrusion protection ([fail2ban](http://www.fail2ban.org/wiki/index.php/Main_Page)), and basic system monitoring ([munin](http://munin-monitoring.org/))

It also includes system management tools:

* Comprehensive health monitoring that checks each day that services are running, ports are open, TLS certificates are valid, and DNS records are correct
* A control panel for adding/removing mail users, aliases, custom DNS records, configuring backups, etc.
* An API for all of the actions on the control panel

It also supports static website hosting since the box is serving HTTPS anyway. (To serve a website for your domains elsewhere, just add a custom DNS "A" record in you Mail-in-a-Box's control panel to point domains to another server.)

For more information on how Mail-in-a-Box handles your privacy, see the [security details page](security.md).


Installation
------------

See the [setup guide](https://mailinabox.email/guide.html) for detailed, user-friendly instructions.

For experts, start with a completely fresh (really, I mean it) Ubuntu 18.04 LTS 64-bit machine. On the machine...

Clone this repository:

	$ git clone https://github.com/mail-in-a-box/mailinabox
	$ cd mailinabox

_Optional:_ Download Josh's PGP key and then verify that the sources were signed
by him:

	$ curl -s https://keybase.io/joshdata/key.asc | gpg --import
	gpg: key C10BDD81: public key "Joshua Tauberer <jt@occams.info>" imported

	$ git verify-tag v0.51
	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

You'll get a lot of warnings, but that's OK. Check that the primary key fingerprint matches the
fingerprint in the key details at [https://keybase.io/joshdata](https://keybase.io/joshdata)
and on his [personal homepage](https://razor.occams.info/). (Of course, if this repository has been compromised you can't trust these instructions.)

Checkout the tag corresponding to the most recent release:

	$ git checkout v0.51

Begin the installation.

	$ sudo setup/start.sh

For help, DO NOT contact Josh directly --- I don't do tech support by email or tweet (no exceptions).

Post your question on the [discussion forum](https://discourse.mailinabox.email/) instead, where maintainers and Mail-in-a-Box users may be able to help you.

Note that while we want everything to "just work," we can't control the rest of the Internet. Other mail services might block or spam-filter email sent from your Mail-in-a-Box.
This is a challenge faced by everyone who runs their own mail server, with or without Mail-in-a-Box. See our discussion forum for tips about that.

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, [May](https://news.ycombinator.com/item?id=9624267) 2015, and [November](https://news.ycombinator.com/item?id=13050500) 2016.
* FastCompany mentioned Mail-in-a-Box a [roundup of privacy projects](http://www.fastcompany.com/3047645/your-own-private-cloud) on June 26, 2015.
