(Power) Mail-in-a-Box

Current Version: v0.44.POWER.1 (Tracking v0.44)

This is a fork of MiaB (duh), hacked and tuned to my needs:

✅ - Done

👨‍💻 - Not there yet, but soon!

💤 - I did not begin this part yet!

• ✅ Proper support for Debian (I recommend Debian Buster or later, but if it works on your machine, it works!);

• • I changed the pre-flight checks to accept Debian and Debian only. If you think you can also make this fork Ubuntu-compatible, shoot a PR or something.

• ✅ Native support for SMTP relays (For example: SendGrid);

• 💤 Ability for "static" pages to use PHP (e.g. host a domain shortener);

• 💤 Custom pages should not have their pages defaulting to the MiaB services (/admin, /mail, etc.);

• 💤 Possibility of disabling some services (*cough* NextCloud *cough*);

• ✅ Bumped the bootstrap and jQuery dependencies' versions - and we've got a brand new admin panel now!

• 💤 Anything else I might need to use;

All in all, I think I should rename this to something like "Central Clown Computing", since I'm trying to cram as many services as possible into that poor machine (Spending 5$ is better than spending 10$)

Original Documentation

By @JoshData and 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 for the project's website and setup guide!

---

Our goals are to:

• Make deploying a good mail server easy.
• Promote decentralization, innovation, and privacy on the web.
• Have automated, auditable, and idempotent configuration.
• Not make a totally unhackable, NSA-proof server.
• Not make something customizable by power users.

Additionally, this project has a Code of Conduct, 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), IMAP (dovecot), CardDAV/CalDAV (Nextcloud), Exchange ActiveSync (z-push)
• Webmail (Roundcube), static website hosting (nginx)
• Spam filtering (spamassassin), greylisting (postgrey)
• DNS (nsd4) with SPF, DKIM (OpenDKIM), DMARC, DNSSEC, DANE TLSA, and SSHFP records automatically set
• Backups (duplicity), firewall (ufw), intrusion protection (fail2ban), system monitoring (munin)

It also includes:

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

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

Installation

See the setup guide 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 v0.44
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 and on his personal homepage. (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 v0.44

Begin the installation.

$ sudo setup/start.sh

The Acknowledgements

This project was inspired in part by the "NSA-proof your email in 2 hours" blog post by Drew Crawford, Sovereign by Alex Payne, and conversations with @shevski, @konklone, and @GregElin.

Mail-in-a-Box is similar to iRedMail and 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, source.
• 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" and making the setup steps reproducible with bash scripts.
• Mail-in-a-Box was a semifinalist in the 2014 Knight News Challenge, but it was not selected as a winner.
• Mail-in-a-Box hit the front page of Hacker News in April 2014, September 2014, May 2015, and November 2016.
• FastCompany mentioned Mail-in-a-Box a roundup of privacy projects on June 26, 2015.
