Version 55 (October 18, 2021) ----------------------------- Mail: * "SMTPUTF8" is now disabled in Postfix. Because Dovecot still does not support SMTPUTF8, incoming mail to internationalized addresses was bouncing. This fixes incoming mail to internationalized domains (which was probably working prior to v0.40), but it will prevent sending outbound mail to addresses with internationalized local-parts. * Upgraded to Roundcube 1.5. Control panel: * The control panel menus are now hidden before login, but now non-admins can log in to access the mail and contacts/calendar instruction pages. * The login form now disables browser autocomplete in the two-factor authentication code field. * After logging in, the default page is now a fast-loading welcome page rather than the slow-loading system status checks page. * The backup retention period option now displays for B2 backup targets. * The DNSSEC DS record recommendations are cleaned up and now recommend changing records that use SHA1. * The Munin monitoring pages no longer require a separate HTTP basic authentication login and can be used if two-factor authentication is turned on. * Control panel logins are now tied to a session backend that allows true logouts (rather than an encrypted cookie). * Failed logins no longer directly reveal whether the email address corresponds to a user account. * Browser dark mode now inverts the color scheme. Other: * Fail2ban's IPv6 support is enabled. * The mail log tool now doesn't crash if there are email addresess in log messages with invalid UTF-8 characters. * Additional nsd.conf files can be placed in /etc/nsd.conf.d. |

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 likemiab.old
-
Clone this repository using:
git clone https://github.com/jrsupplee/mailinabox.git
-
cd into
mailinabox
and runsudo bash setup/bootstrap.sh
On occasion there are lock errors when updatingMunin
. Just re-runsudo 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 themailinabox
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. -
API docs do not include the quota endpoints. Quota API endpoints need to be added to
api/mainlinabox.yml
.

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
Internationalized domain names are supported and configured easily (but SMTPUTF8 is not supported, unfortunately).
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 and checkout the tag corresponding to the most recent release:
$ git clone https://github.com/mail-in-a-box/mailinabox
$ cd mailinabox
$ git checkout v55
Begin the installation.
$ sudo setup/start.sh
The installation will install, uninstall, and configure packages to turn the machine into a working, good mail server.
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.
