 CHANGELOG
 =========
 
+v0.12 (July 3, 2015)
+--------------------
+
+This is a minor update to v0.11, which was a major update. Please read v0.11's advisories.
+
+* v0.12b was posted shortly after the initial posting of v0.12 correcting a minor regression in v0.12 related to creating aliases targetting multiple addresses.
+
+* The administrator@ alias was incorrectly created starting with v0.11. If your first install was v0.11, check that the administrator@ alias forwards mail to you.
+* Intrusion detection rules (fail2ban) are relaxed (i.e. less is blocked).
+* SSL certificates could not be installed for the new automatic 'www.' redirect domains.
+* PHP's default character encoding is changed from no default to UTF8. The effect of this change is unclear but should prevent possible future text conversion issues.
+* User-installed SSL private keys in the BEGIN PRIVATE KEY format were not accepted.
+* SSL certificates with SAN domains with IDNA encoding were broken in v0.11.
+* Some IDNA functionality was using IDNA 2003 rather than IDNA 2008.
+
+
+v0.11 (June 29, 2015)
+---------------------
+
+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.
+* v0.11b was posted shortly after the initial posting of v0.11 correcting a missing dependency for the new PPA.
+
+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.
+

@@ -76,3 +83,4 @@ The History
 * 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, and [May](https://news.ycombinator.com/item?id=9624267) 2015.

-### Domain Policy Records
+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.
 
-Domain policy records allow recipient MTAs to detect when the _domain_ part of 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))
+### 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 basic protocols of email delivery did not plan for the need for encryption. For a number of reasons it is not possible in most cases to guarantee that a connection to a recipient server is secure. However, 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))

Modern encryption settings will be used to the extent the recipient server supports them. ([source](setup/mail-postfix.sh))
 
 ### DANE
 
-The box is [DNSSEC](https://en.wikipedia.org/wiki/DNSSEC)-aware (via a locally running DNSSEC-aware nameserver). When sending outbound mail, 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, which contains a certificate fingerprint, the receiving MTA (server) must support TLS and its certificate must match the fingerprint. In other words, when a DANE TLSA record is published by the recipient, then on-the-wire encryption is forced between the box and the recipient MTA. ([source](setup/mail-postfix.sh))
+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.
