 CHANGELOG
 =========
 
+Version 60.1 (October 30, 2022)
+-------------------------------
+
+* A setup issue where the DNS server nsd isn't running at the end of setup is (hopefully) fixed.
+* Nextcloud is updated to 23.0.10 (contacts to 4.2.2, calendar to 3.5.1).
+
+Version 60 (October 11, 2022)
+-----------------------------
+
+This is the first release for Ubuntu 22.04.
+
+**Before upgrading**, you must **first upgrade your existing Ubuntu 18.04 box to Mail-in-a-Box v0.51 or later**, if you haven't already done so. That may not be possible after Ubuntu 18.04 reaches its end of life in April 2023, so please complete the upgrade well before then. (If you are not using Nextcloud's contacts or calendar, you can migrate to the latest version of Mail-in-a-Box from any previous version.)
+
+For complete upgrade instructions, see:
+
+https://discourse.mailinabox.email/t/version-60-for-ubuntu-22-04-is-about-to-be-released/9558
+
+No major features of Mail-in-a-Box have changed in this release, although some minor fixes were made.
+
+With the newer version of Ubuntu the following software packages we use are updated:
+
+* dovecot is upgraded to 2.3.16, postfix to 3.6.4, opendmark to 1.4 (which adds ARC-Authentication-Results headers), and spampd to 2.53 (alleviating a mail delivery rate limiting bug).
+* Nextcloud is upgraded to 23.0.4 (contacts to 4.2.0, calendar to 3.5.0).
+* Roundcube is upgraded to 1.6.0.
+* certbot is upgraded to 1.21 (via the Ubuntu repository instead of a PPA).
+* fail2ban is upgraded to 0.11.2.
+* nginx is upgraded to 1.18.
+* PHP is upgraded from 7.2 to 8.0.
+
+Also:
+
+* Roundcube's login session cookie was tightened. Existing sessions may require a manual logout.
+* Moved Postgrey's database under $STORAGE_ROOT.
+
+Version 57a (June 19, 2022)
+---------------------------
+
+* The Backblaze backups fix posted in Version 57 was incomplete. It's now fixed.
+
+Version 57 (June 12, 2022)
+--------------------------
+
+Setup:
+
+* Fixed issue upgrading from Mail-in-a-Box v0.40-v0.50 because of a changed URL that Nextcloud is downloaded from.
+
+Backups:
+
+* Fixed S3 backups which broke with duplicity 0.8.23.
+* Fixed Backblaze backups which broke with latest b2sdk package by rolling back its version.
+
+Control panel:
+
+* Fixed spurious changes in system status checks messages by sorting DNSSEC DS records.
+* Fixed fail2ban lockout over IPv6 from excessive loads of the system status checks.
+* Fixed an incorrect IPv6 system status check message.
+
+Version 56 (January 19, 2022)
+-----------------------------
+
+Software updates:
+
+* Roundcube updated to 1.5.2 (from 1.5.0), and the persistent_login and CardDAV (to 4.3.0 from 3.0.3) plugins are updated.
+* Nextcloud updated to 20.0.14 (from 20.0.8), contacts to 4.0.7 (from 3.5.1), and calendar to 3.0.4 (from 2.2.0).
+
+Setup:
+
+* Fixed failed setup if a previous attempt failed while updating Nextcloud.
+
+Control panel:
+
+* Fixed a crash if a custom DNS entry is not under a zone managed by the box.
+* Fix DNSSEC instructions typo.
+
+Other:
+
+* Set systemd journald log retention to 10 days (from no limit) to reduce disk usage.
+* Fixed log processing for submission lines that have a sasl_sender or other extra information.
+* Fix DNS secondary nameserver refesh failure retry period.
+
+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.

-(Power) Mail-in-a-Box
-=====================
+# Power Mail-in-a-Box
+## **[Installation](#installation)** (current version: v60.5)
+## **[Upgrading Quick Start](#upgrading)**
 
-## Installation
+[![ko-fi](https://ko-fi.com/img/githubbutton_sm.svg)](https://ko-fi.com/davness)
 
-- **PRE-REQUISITES:** Debian 10 (Buster) or Ubuntu 20.04 LTS fresh installation
+Power Mail-in-a-Box (a fork of [Mail-in-a-Box](https://mailinabox.email/)) is a complete pre-configured mail appliance, quickly deployable in a matter of minutes.
 
-Update packages:
-```sh
-sudo apt update
-sudo apt full-upgrade
+It's main difference to the main project is focused on ad-hoc, advanced features. While Mail-in-a-Box caters to beginners by providing sane configurations, Power Mail-in-a-Box also attempts to cater to advanced users that want deeper levels of customization.
+
+## Features
+- Configure Power Mail-in-a-Box to use an external SMTP relay;
+- Brand new admin panel (with up-to-date libraries);
+- Perform backups right away from the admin panel;
+- Account quotas support (thanks to **@[jrsupplee](https://github.com/jrsupplee/mailinabox)**!)
+- Customize TTL's for custom DNS records;
+- Publish OpenPGP keys authoritatively via a WKD server;
+- - **In the future:** Allow usage of OpenPGP keys to encrypt backups;
+- Per-domain nginx configuration;
+
+## Goals
+- **Easy of use** - deployment shouldn't take too many technical details to understand. Power Mail-in-a-Box already comes with default configurations which should be good for most users.
+- **Privacy, security and independence** - keeping your mail and data safe from advertisers and prying eyes.
+- **Accessible customizability** - bring the features closer to the people instead of tucking them away in configuration files.
+- **Customizability potential** - allow for deep customization by power users.
+- **Concentration** - all the services you need in just one box.
+- **Support** - support a wide range of operating systems when possible, without compromising the codebase as a whole.
+- **Lightweight** - should be able to run even with very limited resources.
+
+## Non-goals
+- **Scalability** - this appliance is geared towards individuals and small/mid-sized organizations. If your use case is mission-critical it probably is a better idea to shop for a product that provides support.
+- **Portability** - I didn't figure out yet a way to easily transition from Mail-in-a-Box to Power Mail-in-a-Box.
+
+# Minimum Pre-requisites
+The machine this appliance will be installed on needs to have the following specs (or better). Most cloud providers are able to provide VM's that satisfy these specs at relatively low cost.
+
+<small>_These specs depend on the number of users being served and/or amount of traffic_</small>
+- 1 CPU core;
+- 512MB of RAM (**at least 1GB** is recommended);
+- 10GB of disk;
+- **One of the following operating systems:**
+- - Debian GNU/Linux 11 (Bullseye)
+- - Ubuntu LTS 20.04 (Focal Fossa)
+- - Ubuntu LTS 22.04 (Jammy Jellyfish)
+
+## Legacy Support
+The following distributions are no longer supported for the latest version, but they used to be supported at a earlier time:
+- **Debian 10 (Buster)** <= **v56.5**
+
+<small>_These network requirements are usually not provided by residential ISP's. They are not **strictly required** for Power Mail-in-a-Box to install, but it will take more work to get it running as intended._</small>
+- Static, public IPv4 (most residential connections **do not** provide static addresses);
+- - If the machine is behind a NAT, manual configuration might be required.
+- Reverse DNS for that IPv4 address (**Caution:** some cloud providers do not provide this);
+- You should be able to edit the firewall for that address. **In particular, outbound port 25 should not be blocked.**
+
+# Firewall
+If the machine is behind an external firewall or NAT, the following **inbound ports SHOULD** be open to external traffic:
+
+- `25/tcp`
+- `53/tcp`
+- `53/udp`
+- `80/tcp`
+- `443/tcp`
+- `465/tcp`
+- `587/tcp`
+- `993/tcp`
+- `995/tcp`
+- `4190/tcp`
+
+# Installation
+
+1. Power Mail-in-a-Box uses `ufw` to configure it's internal firewall. If your cloud provider requires you to use another tool (usually it does not, but <small>\*cough\* _Oracle Cloud_ \*cough\*</small>), you can follow [these instructions](https://github.com/ddavness/power-mailinabox/discussions/21).
+
+2. Make sure `curl` is installed and locales are configured correctly - you'll want to make sure the primary locale is set to `en_US.UTF-8`:
 ```
-
-Make sure that the `en_US.UTF-8` locale exists and is set as primary (this depends on the image you use)
-```sh
-sudo apt install locales
+sudo apt install curl locales
 sudo dpkg-reconfigure locales
 ```
 
-**Installing Power-Mail-in-a-Box**
-```sh
-curl https://raw.githubusercontent.com/ddavness/power-mailinabox/master/setup/bootstrap.sh | sudo bash
+3. Run the following command, and then follow the instructions that appear on the screen:
+```
+curl -L https://power-mailinabox.net/setup.sh | sudo bash
 ```
 
-## Current Version: v0.54.POWER.5 (Tracking v0.54)
+# Upgrading
 
-This is a fork of MiaB (duh), hacked and tuned to my needs:
+To upgrade an existing box to the latest version, run the same command as you do to perform a new installation:
 
-✅ - **Done**
+```
+curl -L https://power-mailinabox.net/setup.sh | sudo bash
+```
 
-👨‍💻 - **Not there yet, but soon!**
+## Installing or upgrading to a different version
+If for some reason you wish to install a different version (for example, an older version for a workaround, or a beta/release candidate version for testing), you can use the following command.
 
-💤 - **I did not begin this part yet!**
+```
+curl -L https://power-mailinabox.net/<VERSION>/setup.sh | sudo bash
+```
+Where `<VERSION>` is the version you want to install. (**Example:** `v60.0`).
 
-- ✅ Support for Debian AND Ubuntu 20.04 LTS;
-
-- ✅ Native support for SMTP relays (For example: SendGrid);
-
-- ✅ Bumped the bootstrap and jQuery dependencies' versions - and we've got a brand new admin panel now!
-
-- ✅ Per-domain `nginx` configuration: Custom pages will no longer have their pages defaulting to the MiaB services (`/admin`, `/mail`, etc.);
-
-- ✅ Updated NextCloud to the latest version available;
-
-- ✅ Performing backups immediately from the admin panel (independently from the daily schedule);
-
-- 👨‍💻 Encrypting backups using user-provided PGP keys;
-
-- ✅ Integrate a WKD server (Web Key Directory) for PGP keys;
-
-- 💤 Restricting access to the admin panel to certain IP's?
-
-- 💤 Customizing MTA names? (because privacy)
-
-### Ideas section:
-
-- 💤 Ability to download the backups from the admin panel;
-
-- 💤 Possibility of making some services optional (if they require more software to be installed) on setup?
-
-- - For example, one might simply not use NextCloud/Munin at all, and they're there... just wasting resources.
-
-- 💤 AXFR Transfers (for secondary DNS) using TSIG?
-
-- 💤 Expand DNS record options?
-
-- 💤 More complete webmail configuration via the admin panel/plugin management?
-
-- 💤 Expand the TOTP Two-Factor-Authentication for the webmail?
-
-- - Maybe U2F one day, too, but I don't have a capable device for this just yet...
-
-- 💤 Anything else I might need to use;
-
-All in all, I think I should rename this to something like "Central [Clown Computing](https://www.urbandictionary.com/define.php?term=clown%20computing)", since I'm trying to cram as many services as possible into that poor machine (Spending 5$ is better than spending 10$)

-In The Box
-----------
-
-Mail-in-a-Box turns a fresh ~~Ubuntu 18.04 LTS~~ Debian 10 (Buster) 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 and checkout the tag corresponding to the most recent release:
-
-	$ git clone https://github.com/mail-in-a-box/mailinabox
-	$ cd mailinabox
-	$ git checkout v0.54
-
-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.
