 CHANGELOG
 =========
 
+v0.42 (July 4, 2019)
+--------------------
+
+Changes:
+
+* Decreased the minimum supported RAM to 502 Mb.
+* Improved mail client autoconfiguration.
+* Added support for S3-compatible backup services besides Amazon S3.
+* Fixed the control panel login page to let LastPass save passwords.
+* Fixed an error in the user privileges API.
+* Silenced some spurrious messages.
+
+Software updates:
+
+* Upgraded Roundcube from 1.3.8 to 1.3.9.
+* Upgraded Nextcloud from 14.0.6 to 15.0.8 (with Contacts from 2.1.8 to 3.1.1 and Calendar from 1.6.4 to 1.6.5).
+* Upgraded Z-Push from 2.4.4 to 2.5.0.
+
+v0.41 (February 26, 2019)
+-------------------------
+
+System:
+
+* Missing brute force login attack prevention (fail2ban) filters which stopped working on Ubuntu 18.04 were added back.
+* Upgrades would fail if Mail-in-a-Box moved to a different directory in `systemctl link`.
+
+Mail:
+
+* Incoming messages addressed to more than one local user were rejected because of a bug in spampd packaged by Ubuntu 18.04. A workaround was added.
+
+Contacts/Calendar:
+
+* Upgraded Nextcloud from 13.0.6 to 14.0.6.
+* Upgraded Contacts from 2.1.5 to 2.1.8.
+* Upgraded Calendar from 1.6.1 to 1.6.4.
+
+v0.40 (January 12, 2019)
+------------------------
+
+This is the first release for Ubuntu 18.04. This version and versions going forward can **only** be installed on Ubuntu 18.04; however, upgrades of existing Ubuntu 14.04 boxes to the latest version supporting Ubuntu 14.04 (v0.30) continue to work as normal.
+
+When **upgrading**, you **must first upgrade your existing Ubuntu 14.04 Mail-in-a-Box box** to the latest release supporting Ubuntu 14.04 --- that's v0.30 --- before you migrate to Ubuntu 18.04. If you are running an older version of Mail-in-a-Box which has an old version of ownCloud or Nextcloud, you will *not* be able to upgrade your data because older versions of ownCloud and Nextcloud that are required to perform the upgrade *cannot* be run on Ubuntu 18.04. To upgrade from Ubuntu 14.04 to Ubuntu 18.04, you **must create a fresh Ubuntu 18.04 machine** before installing this version. In-place upgrades of servers are not supported. Since Ubuntu's support for Ubuntu 14.04 has almost ended, everyone is encouraged to create a new Ubuntu 18.04 machine and migrate to it.
+
+For complete upgrade instructions, see:
+
+https://discourse.mailinabox.email/t/mail-in-a-box-version-v0-40-and-moving-to-ubuntu-18-04/4289
+
+The changelog for this release follows.
+
+Setup:
+
+* Mail-in-a-Box now targets Ubuntu 18.04 LTS, which will have support from Ubuntu through 2022.
+* Some of the system packages updated in virtue of using Ubuntu 18.04 include postfix (2.11=>3.3) nsd (4.0=>4.1), nginx (1.4=>1.14), PHP (7.0=>7.2), Python (3.4=>3.6), fail2ban (0.8=>0.10), Duplicity (0.6=>0.7).
+* [Unofficial Bash Strict Mode](http://redsymbol.net/articles/unofficial-bash-strict-mode/) is turned on for setup, which might catch previously uncaught issues during setup.
+
+Mail:
+
+* IMAP server-side full text search is no longer supported because we were using a custom-built `dovecot-lucene` package that we are no longer maintaining.
+* Sending email is now disabled on port 25 --- you must log in to port 587 to send email, per the long-standing mail instructions.
+* Greylisting may delay more emails from new senders. We were using a custom-built postgrey package previously that whitelisted sending domains in dnswl.org, but we are no longer maintaining that package.
+
+v0.30 (January 9, 2019)
+-----------------------
+
+Setup:
+
+* Update to Roundcube 1.3.8 and the CardDAV plugin to 3.0.3.
+* Add missing rsyslog package to install line since some OS images don't have it installed by default.
+* A log file for nsd was added.
+
+Control Panel:
+
+* The users page now documents that passwords should only have ASCII characters to prevent character encoding mismaches between clients and the server.
+* The users page no longer shows user mailbox sizes because this was extremely slow for very large mailboxes.
+* The Mail-in-a-Box version is now shown in the system status checks even when the new-version check is disabled.
+* The alises page now warns that alises should not be used to forward mail off of the box. Mail filters within Roundcube are better for that.
+* The explanation of greylisting has been improved.
+
+v0.29 (October 25, 2018)
+------------------------
+
+* Starting with v0.28, TLS certificate provisioning wouldn't work on new boxes until the mailinabox setup command was run a second time because of a problem with the non-interactive setup.
+* Update to Nextcloud 13.0.6.
+* Update to Roundcube 1.3.7.
+* Update to Z-Push 2.4.4.
+* Backup dates listed in the control panel now use an internationalized format.
+
+v0.28 (July 30, 2018)
+---------------------
+
+System:
+
+* We now use EFF's `certbot` to provision TLS certificates (from Let's Encrypt) instead of our home-grown ACME library.
+
+Contacts/Calendar:
+
+* Fix for Mac OS X autoconfig of the calendar.
+
+Setup:
+
+* Installing Z-Push broke because of what looks like a change or problem in their git server HTTPS certificate. That's fixed.
+
+v0.27 (June 14, 2018)
+---------------------
+
+Mail:
+
+* A report of box activity, including sent/received mail totals and logins by user, is now emailed to the box's administrator user each week.
+* Update Roundcube to version 1.3.6 and Z-Push to version 2.3.9.
+
+Control Panel:
+
+* The undocumented feature for proxying web requests to another server now sets X-Forwarded-For.
+
+v0.26c (February 13, 2018)
+--------------------------
+
+Setup:
+
+* Upgrades from v0.21c (February 1, 2017) or earlier were broken because the intermediate versions of ownCloud used in setup were no longer available from ownCloud.
+* Some download errors had no output --- there is more output on error now.
+
+Control Panel:
+
+* The background service for the control panel was not restarting on updates, leaving the old version running. This was broken in v0.26 and is now fixed.
+* Installing your own TLS/SSL certificate had been broken since v0.24 because the new version of openssl became stricter about CSR generation parameters.
+* Fixed password length help text.
+
+Contacts/Calendar:
+
+* Upgraded Nextcloud from 12.0.3 to 12.0.5.
+
+v0.26b (January 25, 2018)
+-------------------------
+
+* Fix new installations which broke at the step of asking for the user's desired email address, which was broken by v0.26's changes related to the control panel.
+* Fix the provisioning of TLS certificates by pinning a Python package we rely on (acme) to an earlier version because our code isn't yet compatible with its current version.
+* Reduce munin's log_level from debug to warning to prevent massive log files.
+
+v0.26 (January 18, 2018)
+------------------------
+
+Security:
+
+* HTTPS, IMAP, and POP's TLS settings have been updated to Mozilla's intermediate cipher list recommendation. Some extremely old devices that use less secure TLS ciphers may no longer be able to connect to IMAP/POP.
+* Updated web HSTS header to use longer six month duration.
+
+Mail:
+
+* Adding attachments in Roundcube broke after the last update for some users after rebooting because a temporary directory was deleted on reboot. The temporary directory is now moved from /tmp to /var so that it is persistent.
+* `X-Spam-Score` header is added to incoming mail.
+
+Control panel:
+
+* RSASHA256 is now used for DNSSEC for .lv domains.
+* Some documentation/links improvements.
+
+Installer:
+
+* We now run `apt-get autoremove` at the start of setup to clear out old packages, especially old kernels that take up a lot of space. On the first run, this step may take a long time.
+* We now fetch Z-Push from its tagged git repository, fixing an installation problem.
+* Some old PHP5 packages are removed from setup, fixing an installation bug where Apache would get installed.
+* Python 3 packages for the control panel are now installed using a virtualenv to prevent installation errors due to conflicts in the cryptography/openssl packages between OS-installed packages and pip-installed packages.
+
+v0.25 (November 15, 2017)
+-------------------------
+
+This update is a security update addressing [CVE-2017-16651, a vulnerability in Roundcube webmail that allows logged-in users to access files on the local filesystem](https://roundcube.net/news/2017/11/08/security-updates-1.3.3-1.2.7-and-1.1.10).
+
+Mail:
+
+* Update to Roundcube 1.3.3.
+
+Control Panel:

+
+Mail:
+
+* Updated to [Roundcube 1.3.1](https://roundcube.net/news/2017/06/26/roundcube-webmail-1.3.0-released), but unfortunately dropping the Vacation plugin because it has not been supported by its author and is not compatible with Roundcube 1.3, and updated the persistent login plugin.
+* Updated to [Z-Push 2.3.8](http://download.z-push.org/final/2.3/z-push-2.3.8.txt).
+* Dovecot now uses stronger 2048 bit DH params for better forward secrecy.
+
+Nextcloud:
+
+* Nextcloud updated to 12.0.3, using PHP7.
+
+Control Panel:
+
+* Nameserver (NS) records can now be set on custom domains.
+* Fix an erroneous status check error due to IPv6 address formatting.
+* Aliases for administrative addresses can now be set to send mail to +tag administrative addresses.
+
+v0.23a (May 31, 2017)
+---------------------
+
+Corrects a problem in the new way third-party assets are downloaded during setup for the control panel, since v0.23.
+
+v0.23 (May 30, 2017)
+--------------------
+
+Mail:
+
+* The default theme for Roundcube was changed to the nicer Larry theme.
+* Exchange/ActiveSync support has been replaced with z-push 2.3.6 from z-push.org (rather than z-push-contrib).
+
+ownCloud (now Nextcloud):
+
+* ownCloud is replaced with Nextcloud 10.0.5.

+---------------------
+
+Mail:
+

+
+* At the end of installation, the SHA256 -- rather than SHA1 -- hash of the system's TLS certificate is shown.
+
+v0.21c (February 1, 2017)
+-------------------------
+
+Installations and upgrades started failing about 10 days ago with the error "ImportError: No module named 'packaging'" after an upstream package (Python's setuptools) was updated by its maintainers. The updated package conflicted with Ubuntu 14.04's version of another package (Python's pip). This update upgrades both packages to remove the conflict.
+
+If you already encountered the error during installation or upgrade of Mail-in-a-Box, this update may not correct the problem on your existing system. See https://discourse.mailinabox.email/t/v0-21c-release-fixes-python-package-installation-issue/1881 for help if the problem persists after upgrading to this version of Mail-in-a-Box.
+
+v0.21b (December 4, 2016)
+-------------------------
+
+This update corrects a first-time installation issue introduced in v0.21 caused by the new Exchange/ActiveSync feature.
+
+v0.21 (November 30, 2016)
+-------------------------
+
+This version updates ownCloud, which may include security fixes, and makes some other smaller improvements.
+
+Mail:
+
+* Header privacy filters were improperly running on the contents of forwarded email --- that's fixed.
+* We have another go at fixing a long-standing issue with training the spam filter (because of a file permissions issue).
+* Exchange/ActiveSync will now use your display name set in Roundcube in the From: line of outgoing email.
+
+ownCloud:
+
+* Updated ownCloud to version 9.1.1.
+
+Control panel:
+
+* Backups can now be made using rsync-over-ssh!
+* Status checks failed if the system doesn't support iptables or doesn't have ufw installed.
+* Added support for SSHFP records when sshd listens on non-standard ports.
+* Recommendations for TLS certificate providers were removed now that everyone mostly uses Let's Encrypt.
+
+System:
+
+* Ubuntu's "Upgrade to 16.04" notice is suppressed since you should not do that.
+* Lowered memory requirements to 512MB, display a warning if system memory is below 768MB.
+
+v0.20 (September 23, 2016)
+--------------------------
+
+ownCloud:
+
+* Updated to ownCloud to 8.2.7.
+
+Control Panel:
+
+* Fixed a crash that occurs when there are IPv6 DNS records due to a bug in dnspython 1.14.0.
+* Improved the wonky low disk space check.
+
+v0.19b (August 20, 2016)
+------------------------
+
+This update corrects a security issue introduced in v0.18.
+
+* A remote code execution vulnerability is corrected in how the munin system monitoring graphs are generated for the control panel. The vulnerability involves an administrative user visiting a carefully crafted URL.
+
+v0.19a (August 18, 2016)
+------------------------
+
+This update corrects a security issue in v0.19.
+
+* fail2ban won't start if Roundcube had not yet been used - new installations probably do not have fail2ban running.
+
+v0.19 (August 13, 2016)
+-----------------------
+
+Mail:
+
+* Roundcube is updated to version 1.2.1.
+* SSLv3 and RC4 are now no longer supported in incoming and outgoing mail (SMTP port 25).
+
+Control panel:
+
+* The users and aliases APIs are now documented on their control panel pages.
+* The HSTS header was missing.
+* New status checks were added for the ufw firewall.
+
+DNS:
+
+* Add SRV records for CardDAV/CalDAV to facilitate autoconfiguration (e.g. in DavDroid, whose latest version didn't seem to work to configure with entering just a hostname).
+
+System:
+
+* fail2ban jails added for SMTP submission, Roundcube, ownCloud, the control panel, and munin.
+* Mail-in-a-Box can now be installed on the i686 architecture.
+
+v0.18c (June 2, 2016)
+---------------------
+
+* Domain aliases (and misconfigured aliases/catch-alls with non-existent local targets) would accept mail and deliver it to new mailbox folders on disk even if the target address didn't correspond with an existing mail user, instead of rejecting the mail. This issue was introduced in v0.18.
+* The Munin Monitoring link in the control panel now opens a new window.
+* Added an undocumented before-backup script.
+
+v0.18b (May 16, 2016)
+---------------------
+
+* Fixed a Roundcube user accounts issue introduced in v0.18.
+
+v0.18 (May 15, 2016)
+--------------------
+
+ownCloud:
+
+* Updated to ownCloud to 8.2.3
+
+Mail:
+
+* Roundcube is updated to version 1.1.5 and the Roundcube login screen now says "[hostname] Webmail" instead of "Mail-in-a-Box/Roundcube webmail".
+* Fixed a long-standing issue with training the spam filter not working (because of a file permissions issue).
+
+Control panel:
+
+* Munin system monitoring graphs are now zoomable.
+* When a reboot is required (due to Ubuntu security updates automatically installed), a Reboot Box button now appears on the System Status Checks page of the control panel.
+* It is now possible to add SRV and secondary MX records in the Custom DNS page.
+* Other minor fixes.
+
+System:
+
+* The fail2ban recidive jail, which blocks long-duration brute force attacks, now no longer sends the administrator emails (which were not helpful).
+
+Setup:
+
+* The system hostname is now set during setup.
+* A swap file is now created if system memory is less than 2GB, 5GB of free disk space is available, and if no swap file yet exists.
+* We now install Roundcube from the official GitHub repository instead of our own mirror, which we had previously created to solve problems with SourceForge.
+* DKIM was incorrectly set up on machines where "localhost" was defined as something other than "127.0.0.1".
+
+v0.17c (April 1, 2016)
+----------------------
+
+This update addresses some minor security concerns and some installation issues.
+
+ownCoud:
+
+* Block web access to the configuration parameters (config.php). There is no immediate impact (see [#776](https://github.com/mail-in-a-box/mailinabox/pull/776)), although advanced users may want to take note.
+
+Mail:
+
+* Roundcube html5_notifier plugin updated from version 0.6 to 0.6.2 to fix Roundcube getting stuck for some people.
+
+Control panel:
+
+* Prevent click-jacking of the management interface by adding HTTP headers.
+* Failed login no longer reveals whether an account exists on the system.
+
+Setup:
+
+* Setup dialogs did not appear correctly when connecting to SSH using Putty on Windows.
+* We now install Roundcube from our own mirror because Sourceforge's downloads experience frequent intermittant unavailability.
+
+v0.17b (March 1, 2016)
+----------------------
+
+ownCloud moved their source code to a new location, breaking our installation script.
+
+v0.17 (February 25, 2016)
+-------------------------
+
+Mail:
+
+* Roundcube updated to version 1.1.4.
+* When there's a problem delivering an outgoing message, a new 'warning' bounce will come after 3 hours and the box will stop trying after 2 days (instead of 5).
+* On multi-homed machines, Postfix now binds to the right network interface when sending outbound mail so that SPF checks on the receiving end will pass.
+* Mail sent from addresses on subdomains of other domains hosted by this box would not be DKIM-signed and so would fail DMARC checks by recipients, since version v0.15.
+
+Control panel:
+
+* TLS certificate provisioning would crash if DNS propagation was in progress and a challenge failed; might have shown the wrong error when provisioning fails.
+* Backup times were displayed with the wrong time zone.
+* Thresholds for displaying messages when the system is running low on memory have been reduced from 30% to 20% for a warning and from 15% to 10% for an error.
+* Other minor fixes.
+
+System:
+
+* Backups to some AWS S3 regions broke in version 0.15 because we reverted the version of boto. That's now fixed.
+* On low-usage systems, don't hold backups for quite so long by taking a full backup more often.
+* Nightly status checks might fail on systems not configured with a default Unicode locale.
+* If domains need a TLS certificate and the user hasn't installed one yet using Let's Encrypt, the administrator would get a nightly email with weird interactive text asking them to agree to Let's Encrypt's ToS. Now just say that the provisioning can't be done automatically.
+* Reduce the number of background processes used by the management daemon to lower memory consumption.
+
+Setup:
+
+* The first screen now warns users not to install on a machine used for other things.
+
+v0.16 (January 30, 2016)
+------------------------
+
+This update primarily adds automatic SSL (now "TLS") certificate provisioning from Let's Encrypt (https://letsencrypt.org/).
+
+Control Panel:
+
+* The SSL certificates (now referred to as "TLS ccertificates") page now supports provisioning free certificates from Let's Encrypt.
+* Report free memory usage.
+* Fix a crash when the git directory is not checked out to a tag.
+* When IPv6 is enabled, check that all domains (besides the system hostname) resolve over IPv6.
+* When a domain doesn't resolve to the box, don't bother checking if the TLS certificate is valid.
+* Remove rounded border on the menu bar.
+
+Other:
+
+* The Sieve port is now open so tools like the Thunderbird Sieve extension can be used to edit mail filters.
+* .be domains now offer DNSSEC options supported by the TLD
+* The daily backup will now email the administrator if there is a problem.
+* Expiring TLS certificates are now automatically renewed via Let's Encrypt.
+* File ownership for installed Roundcube files is fixed.
+* Typos fixed.
+
+v0.15a (January 9, 2016)
+------------------------
+
+Mail:
+
+* Sending mail through Exchange/ActiveSync (Z-Push) had been broken since v0.14 in some setups. This is now fixed.

+# Mail-in-a-Box Code of Conduct
+
+Mail-in-a-Box is an open source community project about working, as a group, to empower ourselves and others to have control over our own digital communications. Just as we hope to increase technological diversity on the Internet through decentralization, we also believe that diverse viewpoints and voices among our community members foster innovation and creative solutions to the challenges we face.
+
+We are committed to providing a safe, welcoming, and harrassment-free space for collaboration, for everyone, without regard to age, disability, economic situation, ethnicity, gender identity and expression, language fluency, level of knowledge or experience, nationality, personal appearance, race, religion, sexual identity and orientation, or any other attribute. Community comes first. This policy supersedes all other project goals.
+
+The maintainers of Mail-in-a-Box share the dual responsibility of leading by example and enforcing these policies as necessary to maintain an open and welcoming environment. All community members should be excellent to each other.
+
+## Scope
+
+This Code of Conduct applies to all places where Mail-in-a-Box community activity is ocurring, including on GitHub, in discussion forums, on Slack, on social media, and in real life. The Code of Conduct applies not only on websites/at events run by the Mail-in-a-Box community (e.g. our GitHub organization, our Slack team) but also at any other location where the Mail-in-a-Box community is present (e.g. in issues of other GitHub organizations where Mail-in-a-Box community members are discussing problems related to Mail-in-a-Box, or real-life professional conferences), or whenever a Mail-in-a-Box community member is representing Mail-in-a-Box to the public at large or acting on behalf of Mail-in-a-Box.
+
+This code does not apply to activity on a server running Mail-in-a-Box software, unless your server is hosting a service for the Mail-in-a-Box community at large.
+
+## Our Standards
+
+Examples of behavior that contributes to creating a positive environment include:
+
+* Using welcoming and inclusive language
+* Being respectful of differing viewpoints and experiences
+* Gracefully accepting constructive criticism
+* Showing empathy towards other community members
+* Making room for new and quieter voices
+
+Examples of unacceptable behavior by participants include:
+
+* The use of sexualized language or imagery and unwelcome sexual attention or advances
+* Trolling, insulting/derogatory/unwelcome comments, and personal or political attacks
+* Public or private harassment
+* Publishing others' private information, such as a physical or electronic address, without explicit permission
+* Aggressive and micro-aggressive behavior, such as unconstructive criticism, providing corrections that do not improve the conversation (sometimes referred to as "well actually"s), repeatedly interrupting or talking over someone else, feigning surprise at someone's lack of knowledge or awareness about a topic, or subtle prejudice (for example, comments like "That's so easy my grandmother could do it.", which is prejudicial toward grandmothers).
+* Other conduct which could reasonably be considered inappropriate in a professional setting
+* Retaliating against anyone who reports a violation of this code.
+
+We will not tolerate harassment. Harassment is any unwelcome or hostile behavior towards another person for any reason. This includes, but is not limited to, offensive verbal comments related to personal characteristics or choices, sexual images or comments, deliberate intimidation, bullying, stalking, following, harassing photography or recording, sustained disruption of discussion or events, nonconsensual publication of private comments, inappropriate physical contact, or unwelcome sexual attention. Conduct need not be intentional to be harassment.
+
+## Enforcement
+
+We will remove, edit, or reject comments, commits, code, wiki edits, issues, and other contributions that are not consistent with this Code of Conduct. We may ban, temporarily or permanently, any contributor for violating this code, when appropriate.
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be reported by contacting the project lead, [Joshua Tauberer](https://razor.occams.info/). All reports will be treated confidentially, impartially, consistently, and swiftly.
+
+Because the need for confidentiality for all parties involved in an enforcement action outweighs the goals of openness, limited information will be shared with the Mail-in-a-Box community regarding enforcement actions that have taken place.
+
+## Attribution
+
+This Code of Conduct is adapted from the [Contributor Covenant, version 1.4](http://contributor-covenant.org/version/1/4) and the code of conduct of [Code for DC](http://codefordc.org/resources/codeofconduct.html).

+# Contributing
+
+Mail-in-a-Box is an open source project. Your contributions and pull requests are welcome.
+
+## Development
+
+To start developing Mail-in-a-Box, [clone the repository](https://github.com/mail-in-a-box/mailinabox) and familiarize yourself with the code.
+
+    $ git clone https://github.com/mail-in-a-box/mailinabox
+
+### Vagrant and VirtualBox
+
+We recommend you use [Vagrant](https://www.vagrantup.com/intro/getting-started/install.html) and [VirtualBox](https://www.virtualbox.org/wiki/Downloads) for development. Please install them first.
+
+With Vagrant set up, the following should boot up Mail-in-a-Box inside a virtual machine:
+
+    $ vagrant up --provision
+
+_If you're seeing an error message about your *IP address being listed in the Spamhaus Block List*, simply uncomment the `export SKIP_NETWORK_CHECKS=1` line in `Vagrantfile`. It's normal, you're probably using a dynamic IP address assigned by your Internet provider–they're almost all listed._
+
+### Modifying your `hosts` file
+
+After a while, Mail-in-a-Box will be available at `192.168.50.4` (unless you changed that in your `Vagrantfile`). To be able to use the web-based bits, we recommend to add a hostname to your `hosts` file:
+
+    $ echo "192.168.50.4 mailinabox.lan" | sudo tee -a /etc/hosts
+
+You should now be able to navigate to https://mailinabox.lan/admin using your browser. There should be an initial admin user with the name `me@mailinabox.lan` and the password `12345678`.
+
+### Making changes
+
+Your working copy of Mail-in-a-Box will be mounted inside your VM at `/vagrant`. Any change you make locally will appear inside your VM automatically.
+
+Running `vagrant up --provision` again will repeat the installation with your modifications.
+
+Alternatively, you can also ssh into the VM using:
+
+    $ vagrant ssh
+
+Once inside the VM, you can re-run individual parts of the setup like in this example:
+
+    vm$ cd /vagrant
+    vm$ sudo setup/owncloud.sh # replace with script you'd like to re-run
+
+### Tests
+
+Mail-in-a-Box needs more tests. If you're still looking for a way to help out, writing and contributing tests would be a great start!

 It also includes:
 
 * A control panel and API for adding/removing mail users, aliases, custom DNS records, etc. and detailed system monitoring.
-* Our own builds of postgrey (adding better whitelisting) and dovecot-lucene (faster search for mail) distributed via the [Mail-in-a-Box PPA](https://launchpad.net/~mail-in-a-box/+archive/ubuntu/ppa) on Launchpad.

-ppa instructions
-================
-
-Mail-in-a-Box maintains a Launchpad.net PPA ([Mail-in-a-Box PPA](https://launchpad.net/~mail-in-a-box/+archive/ubuntu/ppa)) for additional deb's that we want to have installed on systems.
-
-Packages
---------
-
-* postgrey, a fork of [postgrey](http://postgrey.schweikert.ch/) based on the [latest Debian package](http://git.debian.org/?p=collab-maint/postgrey.git), with a modification to whitelist senders that are whitelisted by [dnswl.org](https://www.dnswl.org/) (i.e. don't greylist mail from known good senders).
-
-* dovecot-lucene, [dovecot's lucene full text search plugin](http://wiki2.dovecot.org/Plugins/FTS/Lucene), which isn't built by Ubuntu's dovecot package maintainer unfortunately.
-
-Building
---------
-
-To rebuild the packages in the PPA, you'll need to be @JoshData.
-
-First:
-
-* You should have an account on Launchpad.net.
-* Your account should have your GPG key set (to the fingerprint of a GPG key on your system matching the identity at the top of the debian/changelog files).
-* You should have write permission to the PPA.
-
-To build:
-
-	# Start a clean VM.
-	vagrant up
-
-	# Put your signing keys (on the host machine) into the VM (so it can sign the debs).
-	gpg --export-secret-keys | vagrant ssh -- gpg --import
-
-	# Build & upload to launchpad.
-	vagrant ssh -- "cd /vagrant && make"
-
-Mail-in-a-Box adds our PPA during setup, but if you need to do that yourself for testing:
-
-	apt-add-repository ppa:mail-in-a-box/ppa
-	apt-get update
-	apt-get install postgrey dovecot-lucene
-

-* SSL certificates are generated with 2048-bit RSA keys and SHA-256 fingerprints. The box provides a self-signed certificate by default. The [setup guide](https://mailinabox.email/guide.html) explains how to verify the certificate fingerprint on first login. Users are encouraged to replace the certificate with a proper CA-signed one.

([source](setup/ssl.sh))
 * Only TLSv1, TLSv1.1 and TLSv1.2 are offered (the older SSL protocols are not offered).
-* Export-grade ciphers, the anonymous DH/ECDH algorithms (aNULL), and clear-text ciphers (eNULL) are not offered.
-* The minimum cipher key length offered is 112 bits. The maximum is 256 bits. Diffie-Hellman ciphers use a 2048-bit key for forward secrecy.
+* HTTPS, IMAP, and POP track the [Mozilla Intermediate Ciphers Recommendation](https://wiki.mozilla.org/Security/Server_Side_TLS), balancing security with supporting a wide range of mail clients. Diffie-Hellman ciphers use a 2048-bit key for forward secrecy. For more details, see the [output of SSLyze for these ports](tests/tls_results.txt).
+* SMTP (port 25) uses the Postfix medium grade ciphers and SMTP Submission (port 587) uses the Postfix high grade ciphers ([more info](http://www.postfix.org/postconf.5.html#smtpd_tls_mandatory_ciphers)).
 
 Additionally:
 
 * SMTP Submission (port 587) will not accept user credentials without STARTTLS (true also of SMTP on port 25 in case of client misconfiguration), and the submission port won't accept mail without encryption. The minimum cipher key length is 128 bits. (The box is of course configured not to be an open relay. User credentials are required to send outbound mail.) ([source](setup/mail-postfix.sh))
 * HTTPS (port 443): The HTTPS Strict Transport Security header is set. A redirect from HTTP to HTTPS is offered. The [Qualys SSL Labs test](https://www.ssllabs.com/ssltest) should report an A+ grade. ([source 1](conf/nginx-ssl.conf), [source 2](conf/nginx.conf))
 
-For more details, see the [output of SSLyze for these ports](tests/tls_results.txt).

-The cipher and protocol selection are chosen to support the following clients:
-
-* For HTTPS: Firefox 1, Chrome 1, IE 7, Opera 5, Safari 1, Windows XP IE8, Android 2.3, Java 7.
-* For other protocols: TBD.

+### Brute-force attack mitigation
+
+`fail2ban` provides some protection from brute-force login attacks (repeated logins that guess account passwords) by blocking offending IP addresses at the network level.
+
+The following services are protected: SSH, IMAP (dovecot), SMTP submission (postfix), webmail (roundcube), Nextcloud/CalDAV/CardDAV (over HTTP), and the Mail-in-a-Box control panel & munin (over HTTP).
+
+Some other services running on the box may be missing fail2ban filters.

+`fail2ban` only blocks IPv4 addresses, however. If the box has a public IPv6 address, it is not protected from these attacks.

-# Install a local DNS server, rather than using the DNS server provided by the
-# ISP's network configuration.
+# Install a local recursive DNS server --- i.e. for DNS queries made by
+# local services running on this machine.
 #
-# We do this to ensure that DNS queries
-# that *we* make (i.e. looking up other external domains) perform DNSSEC checks.
-# We could use Google's Public DNS, but we don't want to create a dependency on
-# Google per our goals of decentralization. `bind9`, as packaged for Ubuntu, has
-# DNSSEC enabled by default via "dnssec-validation auto".
+# (This is unrelated to the box's public, non-recursive DNS server that
+# answers remote queries about domain names hosted on this box. For that
+# see dns.sh.)
 #
-# So we'll be running `bind9` bound to 127.0.0.1 for locally-issued DNS queries
-# and `nsd` bound to the public ethernet interface for remote DNS queries asking
-# about our domain names. `nsd` is configured later.
+# The default systemd-resolved service provides local DNS name resolution. By default it
+# is a recursive stub nameserver, which means it simply relays requests to an
+# external nameserver, usually provided by your ISP or configured in /etc/systemd/resolved.conf.
+#
+# This won't work for us for three reasons.
+#
+# 1) We have higher security goals --- we want DNSSEC to be enforced on all
+#    DNS queries (some upstream DNS servers do, some don't).
+# 2) We will configure postfix to use DANE, which uses DNSSEC to find TLS
+#    certificates for remote servers. DNSSEC validation *must* be performed
+#    locally because we can't trust an unencrypted connection to an external
+#    DNS server.
+# 3) DNS-based mail server blacklists (RBLs) typically block large ISP
+#    DNS servers because they only provide free data to small users. Since
+#    we use RBLs to block incoming mail from blacklisted IP addresses,
+#    we have to run our own DNS server. See #1424.
+#
+# systemd-resolved has a setting to perform local DNSSEC validation on all
+# requests (in /etc/systemd/resolved.conf, set DNSSEC=yes), but because it's
+# a stub server the main part of a request still goes through an upstream
+# DNS server, which won't work for RBLs. So we really need a local recursive
+# nameserver.
+#
+# We'll install `bind9`, which as packaged for Ubuntu, has DNSSEC enabled by default via "dnssec-validation auto".
+# We'll have it be bound to 127.0.0.1 so that it does not interfere with
+# the public, recursive nameserver `nsd` bound to the public ethernet interfaces.
 #
 # About the settings:
 #
-# * RESOLVCONF=yes will have `bind9` take over /etc/resolv.conf to tell
-#   local services that DNS queries are handled on localhost.
 # * Adding -4 to OPTIONS will have `bind9` not listen on IPv6 addresses
 #   so that we're sure there's no conflict with nsd, our public domain
 #   name server, on IPV6.
 # * The listen-on directive in named.conf.options restricts `bind9` to
 #   binding to the loopback interface instead of all interfaces.
