Mail-in-a-Box with Quotas

This is an experimental implementation of Mail-in-a-box with quotas. Follow the directions below to install except clone from this repository instead of the official repository.

There is baisc support for quotas in the control panel now. To set quotas from the command line, either use tools/mail.py or set the quota column for the user in the users.sqlite database. If you modify users table using SQL note the following:

• The quota column is text and allows for the M and G suffixes for megabytes and gigabytes respectively.
• No spaces should be used in the quota value (e.g. 2G or 100M).

Please report any bugs on github.

Upgrading v0.40 to v.0.40-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 setup/start.sh with root privileges.

• On occasion there are lock errors when updating Munin. Just re-run setup/start.sh until the error does not occur.

Todo

• Allow Trash to have a grace percentage to allow users whose quota is full to delete messages.

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://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.

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/)), Exchange ActiveSync ([z-push](http://z-push.org/))
* 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](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), and [SSHFP](https://tools.ietf.org/html/rfc4255) records automatically set
* 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/))

It also includes:

* A control panel and API for adding/removing mail users, aliases, custom DNS records, etc. and detailed system monitoring.

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 v0.40
	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 v0.40

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.

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.
