Joshua Tauberer 5faa1cae71 manage the nginx conf in the management daemon too so we can have nginx operate on all domains that we serve mail for 2014-06-20 01:55:12 +00:00
Joshua Tauberer 126ea94ccf drop support for ADSP which since last November is no longer recommended per http://datatracker.ietf.org/doc/status-change-adsp-rfc5617-to-historic/ 2014-06-18 22:56:55 -04:00
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
see #71

Joshua Tauberer 761fac729b nsd.conf wasn't properly using the signed zone files 2014-06-18 23:30:35 +00:00
Joshua Tauberer dd15bf4384 use a better sort order for records in DNS zone files 2014-06-17 23:34:06 +00:00
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

Joshua Tauberer aaa735dbfe write nsd.conf zones in a predictable order so that we don't keep rewriting it 2014-06-12 22:28:37 -04:00
Joshua Tauberer e9cde52a48 two more cases of shelling out external programs in a more secure way, see cecda9cec5 2014-06-12 21:06:04 -04:00
Joshua Tauberer 8bd62aa3bc increase duplicity's volume size from the default of 25MB to 100MB so we create fewer files 2014-06-09 13:47:41 +00:00
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.

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 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 295981828f Vagrantize
* adding a Vagrantfile
* in a non-interactive setup like this, create the user's first email account for them
* let the machine auto-detect its IP address using http://icanhazip.com/
* use our own justtesting.email domain to provision a subdomain for users so they can quickly get started

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.
