v0.11

---------------------

Advisories:
* Users can no longer spoof arbitrary email addresses in outbound mail. When sending mail, the email address configured in your mail client must match the SMTP login username being used, or the email address must be an alias with the SMTP login username listed as one of the alias's targets.
* This update replaces your DKIM signing key with a stronger key. Because of DNS caching/propagation, mail sent within a few hours after this update could be marked as spam by recipients. If you use External DNS, you will need to update your DNS records.
* The box will now install software from a new Mail-in-a-Box PPA on Launchpad.net, where we are distributing two of our own packages: a patched postgrey and dovecot-lucene.

Mail:
* Greylisting will now let some reputable senders pass through immediately.
* Searching mail (via IMAP) will now be much faster using the dovecot lucene full text search plugin.
* Users can no longer spoof arbitrary email addresses in outbound mail (see above).
* Fix for deleting admin@ and postmaster@ addresses.
* Roundcube is updated to version 1.1.2, plugins updated.
* Exchange/ActiveSync autoconfiguration was not working on all devices (e.g. iPhone) because of a case-sensitive URL.
* The DKIM signing key has been increased to 2048 bits, from 1024, replacing the existing key.

Web:
* 'www' subdomains now automatically redirect to their parent domain (but you'll need to install an SSL certificate).
* OCSP no longer uses Google Public DNS.
* The installed PHP version is no longer exposed through HTTP response headers, for better security.

DNS:
* Default IPv6 AAAA records were missing since version 0.09.

Control panel:
* Resetting a user's password now forces them to log in again everywhere.
* Status checks were not working if an ssh server was not installed.
* SSL certificate validation now uses the Python cryptography module in some places where openssl was used.
* There is a new tab to show the installed version of Mail-in-a-Box and to fetch the latest released version.

System:
* The munin system monitoring tool is now installed and accessible at /admin/munin.
* ownCloud updated to version 8.0.4. The ownCloud installation step now is reslient to download problems. The ownCloud configuration file is now stored in STORAGE_ROOT to fix loss of data when moving STORAGE_ROOT to a new machine.
* The setup scripts now run `apt-get update` prior to installing anything to ensure the apt database is in sync with the packages actually available.

+
+v0.10 (June 1, 2015)
+--------------------
+
+* SMTP Submission (port 587) began offering the insecure SSLv3 protocol due to a misconfiguration in the previous version.
+* Roundcube now allows persistent logins using Roundcube-Persistent-Login-Plugin.
+* ownCloud is updated to version 8.0.3.
+* SPF records for non-mail domains were tightened.
+* The minimum greylisting delay has been reduced from 5 minutes to 3 minutes.
+* Users and aliases weren't working if they were entered with any uppercase letters. Now only lowercase is allowed.
+* After installing an SSL certificate from the control panel, the page wasn't being refreshed.
+* Backups broke if the box's hostname was changed after installation.
+* Dotfiles (i.e. .svn) stored in ownCloud Files were not accessible from ownCloud's mobile/desktop clients.
+* Fix broken install on OVH VPS's.
+
+
+v0.09 (May 8, 2015)
+-------------------
+
+Mail:
+
+* Spam checking is now performed on messages larger than the previous limit of 64KB.
+* POP3S is now enabled (port 995).
+* Roundcube is updated to version 1.1.1.
+* Minor security improvements (more mail headers with user agent info are anonymized; crypto settings were tightened).
+
+ownCloud:
+
+* Downloading files you uploaded to ownCloud broke because of a change in ownCloud 8.
+
+DNS:
+
+* Internationalized Domain Names (IDNs) should now work in email. If you had custom DNS or custom web settings for internationalized domains, check that they are still working.
+* It is now possible to set multiple TXT and other types of records on the same domain in the control panel.
+* The custom DNS API was completely rewritten to support setting multiple records of the same type on a domain. Any existing client code using the DNS API will have to be rewritten. (Existing code will just get 404s back.)
+* On some systems the `nsd` service failed to start if network inferfaces were not ready.
+
+System / Control Panel:
+
+* In order to guard against misconfiguration that can lead to domain control validation hijacking, email addresses that begin with admin, administrator, postmaster, hostmaster, and webmaster can no longer be used for (new) mail user accounts, and aliases for these addresses may direct mail only to the box's administrator(s).
+* Backups now use duplicity's built-in gpg symmetric AES256 encryption rather than my home-brewed encryption. Old backups will be incorporated inside the first backup after this update but then deleted from disk (i.e. your backups from the previous few days will be backed up).
+* There was a race condition between backups and the new nightly status checks.
+* The control panel would sometimes lock up with an unnecessary loading indicator.
+* You can no longer delete your own account from the control panel.
+
+Setup:
+
+* All Mail-in-a-Box release tags are now signed on github, instructions for verifying the signature are added to the README, and the integrity of some packages downloaded during setup is now verified against a SHA1 hash stored in the tag itself.
+* Bugs in first user account creation were fixed.
+
+v0.08 (April 1, 2015)
+---------------------
+
+Mail:
+
+* The Roundcube vacation_sieve plugin by @arodier is now installed to make it easier to set vacation auto-reply messages from within Roundcube.
+* Authentication-Results headers for DMARC, added in v0.07, were mistakenly added for outbound mail --- that's now removed.
+* The Trash folder is now created automatically for new mail accounts, addressing a Roundcube error.
+
+DNS:
+
+* Custom DNS TXT records were not always working and they can now override the default SPF, DKIM, and DMARC records.
+
+System:
+
+* ownCloud updated to version 8.0.2.
+* Brute-force SSH and IMAP login attempts are now prevented by properly configuring fail2ban.
+* Status checks are run each night and any changes from night to night are emailed to the box administrator (the first user account).
+
+Control panel:
+
+* The new check that system services are running mistakenly checked that the Dovecot Managesieve service is publicly accessible. Although the service binds to the public network interface we don't open the port in ufw. On some machines it seems that ufw blocks the connection from the status checks (which seems correct) and on some machines (mine) it doesn't, which is why I didn't notice the problem.
+* The current backup chain will now try to predict how many days until it is deleted (always at least 3 days after the next full backup).
+* The list of aliases that forward to a user are removed from the Mail Users page because when there are many alises it is slow and times-out.
+* Some status check errors are turned into warnings, especially those that might not apply if External DNS is used.
+
+v0.07 (February 28, 2015)
+-------------------------
+
+Mail:
+
+* If the box manages mail for a domain and a subdomain of that domain, outbound mail from the subdomain was not DKIM-signed and would therefore fail DMARC tests on the receiving end, possibly result in the mail heading into spam folders.
+* Auto-configuration for Mozilla Thunderbird, Evolution, KMail, and Kontact is now available.
+* Domains that only have a catch-all alias or domain alias no longer automatically create/require admin@ and postmaster@ addresses since they'll forward anyway.
+* Roundcube is updated to version 1.1.0.
+* Authentication-Results headers for DMARC are now added to incoming mail.
+
+DNS:
+
+* If a custom CNAME record is set on a 'www' subdomain, the default A/AAAA records were preventing the CNAME from working.
+* If a custom DNS A record overrides one provided by the box, the a corresponding default IPv6 record by the box is removed since it will probably be incorrect.
+* Internationalized domain names (IDNs) are now supported for DNS and web, but email is not yet tested.
+
+Web:
+
+* Static websites now deny access to certain dot (.) files and directories which typically have sensitive info: .ht*, .svn*, .git*, .hg*, .bzr*.
+* The nginx server no longer reports its version and OS for better privacy.
+* The HTTP->HTTPS redirect is now more efficient.
+* When serving a 'www.' domain, reuse the SSL certificate for the parent domain if it covers the 'www' subdomain too
+* If a custom DNS CNAME record is set on a domain, don't offer to put a website on that domain. (Same logic already applies to custom A/AAAA records.)
 
 Control panel:
 
 * Status checks now check that system services are actually running by pinging each port that should have something running on it.
-* If a custom CNAME record is set on a 'www' subdomain, the default A/AAAA records were preventing the CNAME from working.
+* The status checks are now parallelized so they may be a little faster.
+* The status check for MX records now allow any priority, in case an unusual setup is required.
+* The interface for setting website domain-specific directories is simplified.
+* The mail guide now says that to use Outlook, Outlook 2007 or later on Windows 7 and later is required.
+* External DNS settings now skip the special "_secondary_nameserver" key which is used for storing secondary NS information.
 
 Setup:
 
 * Install cron if it isn't already installed.
 * Fix a units problem in the minimum memory check.
-
+* If you override the STORAGE_ROOT, your setting will now persist if you re-run setup.
-Miscellaneous:
+* Hangs due to apt wanting the user to resolve a conflict should now be fixed (apt will just clobber the problematic file now).
-
-* Internationalized domain names (IDNs) are now supported for DNS and web, but email is not yet tested.
-* Domains that only have a catch-all alias or domain alias no longer automatically create/require admin@ and postmaster@ addresses since they'll forward anyway.

+Mail-in-a-Box turns a fresh Ubuntu 14.04 LTS 64-bit machine into a working mail server by installing and configuring various components.
+
+It is a one-click email appliance (see the [setup guide](https://mailinabox.email/guide.html)). 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 ([ownCloud](http://owncloud.org/)), Exchange ActiveSync ([z-push](https://github.com/fmbiete/Z-Push-contrib))
+* Webmail ([Roundcube](http://roundcube.net/)), static website hosting ([nginx](http://nginx.org/))
+* Spam filtering ([spamassassin](https://spamassassin.apache.org/)), greylisting ([postgrey](http://postgrey.schweikert.ch/))
+* DNS ([nsd4](http://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), and [SSHFP](https://tools.ietf.org/html/rfc4255) records automatically set
+* Firewall ([ufw](https://launchpad.net/ufw)), intrusion protection ([fail2ban](http://www.fail2ban.org/wiki/index.php/Main_Page)), system monitoring ([munin](http://munin-monitoring.org/))
+
+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 and dovecot-lucene distributed via the [Mail-in-a-Box PPA](https://launchpad.net/~mail-in-a-box/+archive/ubuntu/ppa) on Launchpad.
+
+For more information on how Mail-in-a-Box handles your privacy, see the [security details page](security.md).
+
+The Security
+------------
+
+See the [security guide](security.md) for more information about the box's security configuration (TLS, password storage, etc).
+
+I sign the release tags on git. To verify that a tag is signed by me, you can perform the following steps:
+
+	# Download my PGP key.
+	$ curl -s https://keybase.io/joshdata/key.asc | gpg --import
+	gpg: key C10BDD81: public key "Joshua Tauberer <jt@occams.info>" imported
+
+	# Clone this repository.
+	$ git clone https://github.com/mail-in-a-box/mailinabox
+	$ cd mailinabox
+
+	# Verify the tag.
+	$ git verify-tag v0.11
+	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
+
+The key ID and fingerprint above should match my [Keybase.io key](https://keybase.io/joshdata) and the fingerprint I publish on [my homepage](https://razor.occams.info/).

 -----------
 
 * 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).

+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
+

+Mail-in-a-Box Security Guide
+============================
+
+Mail-in-a-Box turns a fresh Ubuntu 14.04 LTS 64-bit machine into a mail server appliance by installing and configuring various components.
+
+This page documents the security features of Mail-in-a-Box. The term “box” is used below to mean a configured Mail-in-a-Box.
+
+Threat Model
+------------
+
+Nothing is perfectly secure, and an adversary with sufficient resources can always penetrate a system.
+
+The primary goal of Mail-in-a-Box is to make deploying a good mail server easy, so we balance ― as everyone does ― privacy and security concerns with the practicality of actually deploying the system. That means we make certain assumptions about adversaries. We assume that adversaries . . .
+
+* Do not have physical access to the box (i.e., we do not aim to protect the box from physical access).
+* Have not been given Unix accounts on the box (i.e., we assume all users with shell access are trusted).
+
+On the other hand, we do assume that adversaries are performing passive surveillance and, possibly, active man-in-the-middle attacks. And so:
+
+* User credentials are always sent through SSH/TLS, never in the clear.
+* Outbound mail is sent with the highest level of TLS possible (more on that below).
+
+User Credentials
+----------------
+
+The box's administrator and its (non-administrative) mail users must sometimes communicate their credentials to the box.
+
+### Services behind TLS
+
+These services are protected by [TLS](https://en.wikipedia.org/wiki/Transport_Layer_Security):
+
+* SMTP Submission (port 587). Mail users submit outbound mail through SMTP with STARTTLS on port 587.
+* IMAP/POP (ports 993, 995). Mail users check for incoming mail through IMAP or POP over TLS.
+* HTTPS (port 443). Webmail, the Exchange/ActiveSync protocol, the administrative control panel, and any static hosted websites are accessed over HTTPS.
+
+The services all follow these rules:
+
+* 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.
+
+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.
+
+### Password Storage
+
+The passwords for mail users are stored on disk using the [SHA512-CRYPT](http://man7.org/linux/man-pages/man3/crypt.3.html) hashing scheme. ([source](management/mailconfig.py))
+
+When using the web-based administrative control panel, after logging in an API key is placed in the browser's local storage (rather than, say, the user's actual password). The API key is an HMAC based on the user's email address and current password, and it is keyed by a secret known only to the control panel service. By resetting an administrator's password, any HMACs previously generated for that user will expire.
+
+### Console access
+
+Console access (e.g. via SSH) is configured by the system image used to create the box, typically from by a cloud virtual machine provider (e.g. Digital Ocean). Mail-in-a-Box does not set any console access settings, although it will warn the administrator in the System Status Checks if password-based login is turned on.
+
+The [setup guide video](https://mailinabox.email/) explains how to verify the host key fingerprint on first login.
+
+If DNSSEC is enabled at the box's domain name's registrar, the SSHFP record that the box automatically puts into DNS can also be used to verify the host key fingerprint by setting `VerifyHostKeyDNS yes` in your `ssh/.config` file or by logging in with `ssh -o VerifyHostKeyDNS=yes`. ([source](management/dns_update.py))
+
+Outbound Mail
+-------------
+
+The basic protocols of email delivery did not plan for the presence of adversaries on the network. For a number of reasons it is not possible in most cases to guarantee that a connection to a recipient server is secure.
+
+### DNSSEC
+
+The first step in resolving the destination server for an email address is performing a DNS look-up for the MX record of the domain name. The box uses a locally-running [DNSSEC](https://en.wikipedia.org/wiki/DNSSEC)-aware nameserver to perform the lookup. If the domain name has DNSSEC enabled, DNSSEC guards against DNS records being tampered with.
+
+### Encryption
+
+The box (along with the vast majority of mail servers) uses [opportunistic encryption](https://en.wikipedia.org/wiki/Opportunistic_encryption), meaning the mail is encrypted in transit and protected from passive eavesdropping, but it is not protected from an active man-in-the-middle attack. Modern encryption settings will be used to the extent the recipient server supports them. ([source](setup/mail-postfix.sh))
+
+### DANE
+
+If the recipient's domain name supports DNSSEC and has published a [DANE TLSA](https://en.wikipedia.org/wiki/DNS-based_Authentication_of_Named_Entities) record, then on-the-wire encryption is forced between the box and the recipient MTA and this encryption is not subject to a man-in-the-middle attack. The TLSA record contains a certificate fingerprint which the receiving MTA (server) must present to the box. ([source](setup/mail-postfix.sh))
+
+### Domain Policy Records
+
+Domain policy records allow recipient MTAs to detect when the _domain_ part of of the sender address in incoming mail has been spoofed. All outbound mail is signed with [DKIM](https://en.wikipedia.org/wiki/DomainKeys_Identified_Mail) and "quarantine" [DMARC](https://en.wikipedia.org/wiki/DMARC) records are automatically set in DNS. Receiving MTAs that implement DMARC will automatically quarantine mail that is "From:" a domain hosted by the box but which was not sent by the box. (Strong [SPF](https://en.wikipedia.org/wiki/Sender_Policy_Framework) records are also automatically set in DNS.) ([source](management/dns_update.py))
+
+### User Policy
+
+While domain policy records prevent other servers from sending mail with a "From:" header that matches a domain hosted on the box (see above), those policy records do not guarnatee that the user portion of the sender email address matches the actual sender. In enterprise environments where the box may host the mail of untrusted users, it is important to guard against users impersonating other users. The box restricts the envelope sender address that users may put into outbound mail to either a) their own email address (their SMTP login username) or b) any alias that they are listed as a direct recipient of. Note that the envelope sender address is not the same as the "From:" header.
+
+Incoming Mail
+-------------
+
+### Encryption
+
+As discussed above, there is no way to require on-the-wire encryption of mail. When the box receives an incoming email (SMTP on port 25), it offers encryption (STARTTLS) but cannot require that senders use it because some senders may not support STARTTLS at all and other senders may support STARTTLS but not with the latest protocols/ciphers. To give senders the best chance at making use of encryption, the box offers protocols back to SSLv3 and ciphers with key lengths as low as 112 bits. Modern clients (senders) will make use of the 256-bit ciphers and Diffie-Hellman ciphers with a 2048-bit key for forward secrecy, however. ([source](setup/mail-postfix.sh))
+
+### DANE
+
+When DNSSEC is enabled at the box's domain name's registrar, [DANE TLSA](https://en.wikipedia.org/wiki/DNS-based_Authentication_of_Named_Entities) records are automatically published in DNS. Senders supporting DANE will enforce encryption on-the-wire between them and the box --- see the section on DANE for outgoing mail above. ([source](management/dns_update.py))
+
+### Filters
+
+Incoming mail is run through several filters. Email is bounced if the sender's IP address is listed in the [Spamhaus Zen blacklist](http://www.spamhaus.org/zen/) or if the sender's domain is listed in the [Spamhaus Domain Block List](http://www.spamhaus.org/dbl/). Greylisting (with [postgrey](http://postgrey.schweikert.ch/)) is also used to cut down on spam. ([source](setup/mail-postfix.sh))
