Joshua Tauberer 8042ab66ac dont serve web for domains with custom DNS records that point A/AAAA elsewhere, and in whats_next only check that an A record exists on a domain if we are serving web on the domain 2014-07-20 15:23:17 +00:00

sfPlayer1 0e893626c8 Add IPv6 glue records as well
The dns_update script didn't generate IPv6 (AAAA) glue records for the name servers.

This caused http://dnscheck.pingdom.com to complain about a mismatch between the glue records reported by the parent name server and mailinabox nsd.

Here's the failing dnscheck output for reference:
> Checking glue for ns1.my.domain.tld (1.2.3.4).
> Child glue for bgwe.eu found: ns1.my.domain.tld (1.2.3.4)
> Checking glue for ns1.my.domain.tld (1234::1).
> Missing glue at child: ns1.my.domain.tld
> Checking glue for ns2.my.domain.tld (1.2.3.4).
> Child glue for bgwe.eu found: ns2.my.domain.tld (1.2.3.4)
> Checking glue for ns2.my.domain.tld (1234::1).
> Missing glue at child: ns2.my.domain.tld

I'm not very familiar with Python and DNS, please verify ;)

Joshua Tauberer 42c891032d don't create a www. subdomain on any domains that are themselves subdomains within a zone, i.e. don't create www.PUBLIC_HOSTNAME if PUBLIC_HOSTNAME is a subdomain of another domain, which is what we normally recommend 2014-07-17 13:08:05 +00:00

Moved the configuration to a single YAML file, rather than one per domain, to be clearer.

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 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

Michael Kropat ae67409603 Support dual-stack IPv4/IPv6 mail servers
Addresses #3

Added support by adding parallel code wherever `$PUBLIC_IP` was used.
Providing an IPv6 address is completely optional.

Playing around on my IPv6-enabled mail server revealed that — before
this change — mailinabox might try to use an IPv6 address as the value
for `$PUBLIC_IP`, which wouldn't work out well.

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.
