+CHANGELOG
+=========
+
+v0.06 (January 4, 2015)
+-----------------------
+
+Mail:
+
+* Set better default system limits to accommodate boxes handling mail for 20+ users.
+
+Contacts/calendar:
+
+* Update to ownCloud to 7.0.4.
+* Contacts syncing via ActiveSync wasn't working.
+
+Control panel:
+
+* New control panel for setting custom DNS settings (without having to use the API).
+* Status checks showed a false positive for Spamhause blacklists and for secondary DNS in some cases.
+* Status checks would fail to load if openssh-sever was not pre-installed, but openssh-server is not required.
+* The local DNS cache is cleared before running the status checks using 'rncd' now rather than restarting 'bind9', which should be faster and wont interrupt other services.
+* Multi-domain and wildcard certificate can now be installed through the control panel.
+* The DNS API now allows the setting of SRV records.
+
+Misc:
+
+* IPv6 configuration error in postgrey, nginx.
+* Missing dependency on sudo.
+
+v0.05 (November 18, 2014)
+-------------------------
+
+Mail:
+
+* The maximum size of outbound mail sent via webmail and Exchange/ActiveSync has been increased to 128 MB, the same as when using SMTP.
+* Spam is no longer wrapped as an attachment inside a scary Spamassassin explanation. The original message is simply moved straight to the Spam folder unchanged.
+* There is a new iOS/Mac OS X Configuration Profile link in the control panel which makes it easier to configure IMAP/SMTP/CalDAV/CardDAV on iOS devices and Macs.
+* "Domain aliases" can now be configured in the control panel.
+* Updated to [Roundcube 1.0.3](http://trac.roundcube.net/wiki/Changelog).
+* IMAP/SMTP is now recommended even on iOS devices as Exchange/ActiveSync is terribly buggy.
+
+Control panel:
+
+* Installing an SSL certificate for the primary hostname would cause problems until a restart (services needed to be restarted).
+* Installing SSL certificates would fail if /tmp was on a different filesystem.
+* Better error messages when installing a SSL certificate fails.
+* The local DNS cache is now cleared each time the system status checks are run.
+* Documented how to use +tag addressing.
+* Minor UI tweaks.
+
+Other:
+
+* Updated to [ownCloud 7.0.3](http://owncloud.org/changelog/).
+* The ownCloud API is now exposed properly.
+* DNSSEC now works on `.guide` domains now too (RSASHA256).
+
+v0.04 (October 15, 2014)
+------------------------
+
+Breaking changes:
+
+* On-disk backups are now retained for a minimum of 3 days instead of 14. Beyond that the user is responsible for making off-site copies.
+* IMAP no longer supports the legacy SSLv3 protocol. SSLv3 is now known to be insecure. I don't believe any modern devices will be affected by this. HTTPS and SMTP submission already had SSLv3 disabled.
+
+Control panel:
+
+* The control panel has a new page for installing SSL certificates.
+* The control panel has a new page for hosting static websites.
+* The control panel now shows mailbox sizes on disk.
+* It is now possible to create catch-all aliases from the control panel.
+* Many usability improvements in the control panel.
+
+DNS:
+
+* Custom DNS A/AAAA records on subdomains were ignored.
+* It is now possible to set up a secondary DNS server.
+* DNS zones were updating even when nothing changed.
+* Strict SPF and DMARC settings are now set on all subdomains not used for mail.
+
+Security:
+
+* DNSSEC is now supported for the .email TLD which required a different key algorithm.
+* Nginx and Postfix now use 2048 bits of DH parameters instead of 1024.
+
+Other:
+
+* Spam filter learning by dragging mail in and out of the Spam folder should hopefully be working now.
+* Some things were broken if the machine had an IPv6 address.
+* Other things were broken if the machine was on a non-utf8 locale.
+* No longer implementing webfinger.
+* Removes apache before installing nginx, in case it has been installed by distro.
+
+v0.03 (September 24, 2014)
+--------------------------
+
+* Update existing installs of Roundcube.
+* Disabled catch-alls pending figuring out how to get users to take precedence.
+* Z-Push was not working because in v0.02 we had accidentally moved to a different version.
+* Z-Push is now locked to a specific commit so it doesn't change on us accidentally.
+* The start script is now symlinked to /usr/local/bin/mailinabox.
+
+v0.02 (September 21, 2014)
+--------------------------
+
+* Open the firewall to an alternative SSH port if set.
+* Fixed missing dependencies.
+* Set Z-Push to use sync command with ownCloud.
+* Support more concurrent connections for z-push.
+* In the status checks, handle wildcard certificates.
+* Show the status of backups in the control panel.
+* The control panel can now update a user's password.
+* Some usability improvements in the control panel.
+* Warn if a SSL cert is expiring in 30 days.
+* Use SHA2 to generate CSRs.
+* Better logic for determining when to take a full backup.
+* Reduce DNS TTL, not that it seems to really matter.
+* Add SSHFP DNS records.
+* Add an API for setting custom DNS records 
+* Update to ownCloud 7.0.2.
+* Some things were broken if the machine had an IPv6 address.
+* Use a dialogs library to ask users questions during setup.
+* Other fixes.

 Mail-in-a-Box
 =============
 
-By [@JoshData](https://github.com/JoshData) and contributors.
+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.
 
-**This is a work in progress. I work on this in my limited free time.**
+**Please see [https://mailinabox.email](https://mailinabox.email) for the project's website and setup guide!**
 
-Why build this? Mass electronic surveillance by governments revealed over the last year has spurred a new movement to [re-decentralize](http://redecentralize.org/) the web, that is, to empower netizens to be their own service providers again. SMTP, the protocol of email, is decentralized in principle but highly centralized in practice due to the high cost of implementing all of the modern protocols that surround it. As a result, most individuals trade their independence for access to a “free” email service.
+* * *
 
+I am trying to:
+
+* Make deploying a good mail server easy.
+* Promote [decentralization](http://redecentralize.org/), innovation, and privacy on the web.
+* Have automated, auditable, and [idempotent](http://sharknet.us/2014/02/01/automated-configuration-management-challenges-with-idempotency/) configuration.
+* **Not** be a mail server that the NSA cannot hack.
+* **Not** be customizable by power users.
+
+The long-term goal is to have this be a one-click email appliance with *no* user-configurable setup options.
+
+For more background, see [The Rationale](https://github.com/mail-in-a-box/mailinabox/wiki).
+
+This setup is what has been powering my own personal email since September 2013.
 
 The Box
 -------
 
-Mail-in-a-Box turns a fresh Ubuntu 14.04 LTS 64-bit machine into a working mail server, including SMTP ([postfix](http://www.postfix.org/)), IMAP ([dovecot](http://dovecot.org/)), Exchange ActiveSync ([z-push](https://github.com/fmbiete/Z-Push-contrib)), webmail ([Roundcube](http://roundcube.net/)), spam filtering ([spamassassin](https://spamassassin.apache.org/)), greylisting ([postgrey](http://postgrey.schweikert.ch/)), CardDAV/CalDAV ([ownCloud](http://owncloud.org/)), DNS, [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 basic system services like a firewall, intrusion protection, and setting the system clock.

-
-This setup is what has been powering my own personal email since September 2013.
-
-Please see [mailinabox.email](https://mailinabox.email) for more information and how to set up a Mail-in-a-Box.
-
-In short, it's like this:
-
-	# do this on a fresh install of Ubuntu 14.04 only!
-	sudo apt-get install -y git
-	git clone https://github.com/mail-in-a-box/mailinabox
-	cd mailinabox
-	sudo setup/start.sh
-
-Congratulations! You should now have a working setup. You'll be given the address of the administrative interface for further instructions.
-
-**Status**: This is a work in progress. It works for what it is, but it is missing such things as quotas, backup/restore, etc.
-
-The Goals
----------
-
-* Create a push-button "Email Appliance" for everyday users.
-* Promote decentralization, innovation, and privacy on the web.
-* Have automated, auditable, and [idempotent](http://sharknet.us/2014/02/01/automated-configuration-management-challenges-with-idempotency/) configuration.
-
-For more background, see [The Rationale](https://github.com/mail-in-a-box/mailinabox/wiki).
-
-What I am not trying to do:
-
-* **Not** to be a mail server that the NSA cannot hack.
-* **Not** to be customizable by power users.

 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).
 * 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) and [September](https://news.ycombinator.com/item?id=8276171) 2014.

+<h3>Using a Secondary Nameserver</h3>

If you choose to use a seconday/slave nameserver, you must find a seconday/slave nameserver service provider. Your domain name registrar or virtual cloud provider may provide this service for you. Once you set up the seconday/slave nameserver service, enter the hostname of <em>their</em> secondary nameserver:</p>

+

+
+<p>Send a POST request like this:</p>
+
+<pre>curl -d "" --user {email}:{password} https://{{hostname}}/admin/dns/set/<b>qname</b>[/<b>rtype</b>[/<b>value</b>]]</pre>
+
+<h4>HTTP POST parameters</h4>
+
+<table class="table">
+<thead><th>Parameter</th> <th>Value</th></thead>
+<tr><td>email</td> <td>The email address of any administrative user here.</td></tr>
+<tr><td>password</td> <td>That user&rsquo;s password.</td></tr>
+<tr><td>qname</td> <td>The fully qualified domain name for the record you are trying to set.</td></tr>
+<tr><td>rtype</td> <td>The resource type. <code>A</code> if omitted. Possible values: <code>A</code> (an IPv4 address), <code>AAAA</code> (an IPv6 address), <code>TXT</code> (a text string), or <code>CNAME</code> (an alias, which is a fully qualified domain name).</td></tr>
+<tr><td>value</td> <td>The new record&rsquo;s value. If omitted, the IPv4 address of the remote host is used. This is handy for dynamic DNS! To delete a record, use &ldquo;__delete__&rdquo;.</td></tr>
+</table>
+
+<p style="margin-top: 1em">Note that <code>-d ""</code> is merely to ensure curl sends a POST request. You do not need to put anything inside the quotes. You can also pass the value using typical form encoding in the POST body.</p>
+
+<p>Strict <a href="http://tools.ietf.org/html/rfc4408">SPF</a> and <a href="https://datatracker.ietf.org/doc/draft-kucherawy-dmarc-base/?include_text=1">DMARC</a> records will be added to all custom domains unless you override them.</p>

+curl -d "" --user me@mydomain.com:###### https://{{hostname}}/admin/dns/set/laptop.mydomain.com
+
+# sets an alias
+curl -d "" --user me@mydomain.com:###### https://{{hostname}}/admin/dns/set/foo.mydomain.com/cname/bar.mydomain.com
+
+# clears the alias
+curl -d "" --user me@mydomain.com:###### https://{{hostname}}/admin/dns/set/bar.mydomain.com/cname/__delete__
+
+# sets a TXT record using the alternate value syntax
+curl -d "value=something%20here" --user me@mydomain.com:###### https://{{hostname}}/admin/dns/set/foo.mydomain.com/txt

+<h2>Static Web Hosting</h2>
+
+<p>This machine is serving a simple, static website at <a href="https://{{hostname}}">https://{{hostname}}</a> and at all domain names that you set up an email user or alias for.</p>
+
+<h3>Uploading web files</h3>
+
+<p>You can replace the default website with your own HTML pages and other static files. This control panel won&rsquo;t help you design a website, but once you have <tt>.html</tt> files you can upload it following these instructions:</p>
+
+<ol>
+<li>Ensure that any domains you are publishing a website for have no problems on the <a href="#system_status" onclick="return show_panel(this);">Status Checks</a> page.</li>
+
+<li>On your personal computer, install an SSH file transfer program such as <a href="https://filezilla-project.org/">FileZilla</a> or <a href="http://linuxcommand.org/man_pages/scp1.html">scp</a>.</li>
+
+<li>Log in to this machine with the file transfer program. The server is <strong>{{hostname}}</strong>, the protocol is SSH or SFTP, and use the <strong>SSH login credentials</strong> that you used when you originally created this machine at your cloud host provider. This is <strong>not</strong> what you use to log in either for email or this control panel. Your SSH credentials probably involves a private key file.</li>
+
+<li>Upload your <tt>.html</tt> or other files to the directory <tt>{{storage_root}}/www/default</tt> on this machine. They will appear directly and immediately on the web.</li>
