Joshua Tauberer 45d47818ca add changelog entry for 4f98d470a0 2015-05-28 13:12:57 +00:00
Joshua Tauberer 202c4a948b our users/aliases database is case sensitive - force new users/aliases to lowercase
Unfortunately our users/aliases database is case sensitive. (Perhaps I should have defined the columns with COLLATE NOCASE, see https://www.sqlite.org/datatype3.html.) Postfix always queries the tables in lowecase, so mail delivery would fail if a user or alias were defined with any capital letters. It would have also been possible to add multiple euqivalent addresses into the database with different case.

This commit rejects new mail users that have capital letters and forces new aliases to lowecase. I prefer to reject rather than casefold user accounts so that the login credentials the user gave are exactly what goes into the database.

David Piggott d6c5f09a1a Use lowercase h for consistency in aliases template - it reads better (IMO!)
This also includes fixes for a typo and some whitespace inconsistencies in
mailconfig.py. In fact the capitalisation change and those fixes are the
remnants of a patch I had been running that changed the default aliases - it
was through developing it that I found the issues.

(I wanted to bring the number of patches I apply before deploying to zero and
in the case of this one I've come to view the way MIAB already is as superior,
so I've undone the core of my patch and these tiny issues are all that remain).

Joshua Tauberer 4f98d470a0 '/dev/stdout' does not exist on some systems (!)
The OVH VPS provider creates systems without /dev/stdout. I have never seen that before. But fine. We were passing it as a command line option to `openssl req`, but outputting to stdout is the default so it's not necessary to specify /dev/stdout.

Fixes #277. Also https://discourse.mailinabox.email/t/500-internal-server-error/475/10.

=====

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.

Joshua Tauberer e39b777abc require TLS on SMTP submission (port 587) to prevent accidental client misconfiguration, although this has no other practical consequences since without TLS clients couldn't authenticate anyway 2015-05-06 00:25:03 +00:00
Joshua Tauberer 7ca42489ae drop legacy, export-grade, and anonymous ciphers from SMTP (port 25, opportunistic)
Even though SMTP (on port 25) is typically opportunistic and a MitM attack can't be prevented, we may as well only offer ciphers that provide some level of security. If a client is so old or misconfigured that it doesn't support newer ciphers, it should hopefully fall back to a non-TLS connection.

Postfix's default was basically anything goes (anonymous and 40-bit ciphers!). Google's MTA's only offer ciphers at 112 bits at greater, and this change approximates that with Postfix's "medium" setting.

Fixes #371

Joshua Tauberer 8c6363f792 bad ciphers were allowed in smtp submssion
This disallows aNULL and other bad ciphers in the Postfix submission server.

I missed an option in 45e93f7dcc recommended by the blog post I was reading.

Fixes #389.

Joshua Tauberer a07de38e80 remove workaround for buggy nsd installation
Prior to nsd 4.0.1-1ubuntu0.1, we had to create the nsd user before installing the nsd package.

This was our issue #25 (see 4e6037c0e1, c7e1e29d) and I reported it upstream at https://bugs.launchpad.net/ubuntu/+source/nsd/+bug/1311886. The new package was published by Ubuntu on 2015-01-15 so this work-around is no longer needed.
