Joshua Tauberer 0f72f78eea add DNSSEC/DANE TLSA to the README 2014-06-19 02:23:07 +00:00
Joshua Tauberer 782ad04b10 use DANE when sending mail: if the recipient MX has a DANE TLSA record in DNS then Postfix will necessarily encrypt the mail in transport 2014-06-19 01:58:14 +00:00
Joshua Tauberer 95e61bc110 add DANE TLSA records to the PUBLIC_HOSTNAME's DNS 
Postfix has a tls_security_level called "dane" which uses DNS-Based Authentication of Named Entities (DANE)
to require, if specified in the DNS of the MX host, an encrpyted connection with a known certificate.

This commit adds TLSA records.

Joshua Tauberer 699bccad80 missing spaces in nsd.conf (has no effect but looks proper) 2014-06-18 23:53:52 +00:00
Joshua Tauberer afb6c26c8b run bind9 on the loopback interface for ensuring we are using a DNSSEC-aware nameserver to resolve our own DNS queries (i.e. when sending mail) since we can't trust that the network configuration provided for us gives us a DNSSEC-aware DNS server

Joshua Tauberer 14396e58f8 dont create a separate zone for PUBLIC_HOSTNAME if it is a subdomain of another zone (hmm, this is a general principle that could apply to any two domains the box is serving) 2014-06-17 23:30:00 +00:00

Now that dns_update is a part of the management daemon, we no
longer are using STORAGE_ROOT/dns for anything.

Joshua Tauberer 5490142df5 re-do the backup script to use the duplicity program 
Duplicity will manage the process of creating incremental backups for us.
Although duplicity can both encrypt & copy files to a remote host, I really
don't like PGP and so I don't want to use that.

Instead, we'll back up to a local directory unencrypted, then manually
encrypt the full & incremental backup files. Synchronizing the encrypted
backup directory to a remote host is a TODO.

Joshua Tauberer cd1802fecc Filter privacy-sensitive headers on outgoing mail 
This re-implements part of PR #69 by @mkropat, who wrote:

By default, Postfix adds a Received header — on all mail that you send —
that lists the IP of the device you sent the mail from.  This feature is
great if you're a mail provider and you need to debug why one user is
having sending issues.  This feature is not so great if you run your own
mail server and you don't want every recipient of every email you send
to know the device and IP you sent the email from.

To limit this filtering to outgoing mail only, we apply the filters just
to the submission port.  See these guides [1] [2] for more context.

* using it to enable the Postfix submission service
* per @mkropat's suggestion in #69, set an option to distinguish submission from regular smpd in syslog by giving submission a new name (doing this here to test that editconf is working right on master.cf)

Joshua Tauberer 242cadebc8 allow dashes in emails during validation, and for aliases allow a much wider range of characters, fixes #64 
* for local mail users, also disallows periods at the beginning or end of the local or domain parts
* Dovecot gets confused if the string contains any unusual characters, so local mail users are restricted to a narrow regex
* for mail aliases Postfix is not confused so use a regex based on RFC 2822

Joshua Tauberer 389c354c8f Vagrant updates 
* use a public box (the official Ubuntu 14.04 box which contra the description does have VBox Guest Additions installed)
* now that we allow SSH password logins, since Vagrant requires it, dont muck with sshd_config here
* don't put the machine on the public network because that will allow anyone to log into it with Vagrant's default username/password, duh

Joshua Tauberer c54b0cbefc move management into a daemon service running as root 
* Created a new Python/flask-based management daemon.
* Moved the mail user management core code from tools/mail.py to the new daemon.
* tools/mail.py is a wrapper around the daemon and can be run as a non-root user.
* Adding a new initscript for the management daemon.
* Moving dns_update.sh to the management daemon, called via curl'ing the daemon's API.

This also now runs the DNS update after mail users and aliases are added/removed,
which sets up new domains' DNS as needed.

Joshua Tauberer cfcb5f5bbd merge: @PirosB3 and @pjz suggested using pjzz/phusion-baseimage as the base image for docker 
See http://phusion.github.io/baseimage-docker/ for why the stock Ubuntu
image from Docker is not good enough for a complex system.

Thanks to @pjz for updating the base image for Ubuntu 14.04 and starting
the service scripts.

Joshua Tauberer 19f5f144ae installing roundcube from debian would cause update from ubuntu later, now install from Ubuntu debs 
We were installing .deb's from Debian. The next apt-get upgrade would cause roundcube to be upgraded.
Maybe that also triggered the installation of apache. Now install roundcube from Ubuntu. So long as
Ubuntu doesn't post an update to roundcube, at least it won't trigger an upgrade on the next
apt-get upgrade. This should also mean we don't need to purge the installation of apache2.

Also try using apt-mark hold to prevent roundcube from being updated, in case that will trigger
dependencies.
