run status checks each night and email the administrator with the changes from the previous day's results

If the migration file is missing but the storage directory exists, assume this is a fresh directory -- don't bother trying to migrate, and do write the migration file with the current migration ID.

Update MX records using DNS Update API / Management UI

Give the DNS update tool the ability to customize MX records. Useful if you want a subdomain to send mail to another host.

Changed MX check to respect priorities other than 10.

The status check on MX records now correctly handles domains with
multiple MX records.

Reordered the if a little, added some string parsing, and modified the
OK text to include a warning.

Do not show '_secondary_nameserver' in Custom DNS table

It's redundant and potentially confusing, as any secondary NS shows in "Using a
Secondary Nameserver".

when serving a 'www.' domain, check if the parent domain's ssl certificate can be used besides checking PRIMARY_HOSTNAME

Removing buy_certificate.py which is not working and I don't want to update its call signatures.

all mail domains, not just (top-level) zones, must have an entry in the opendkim key tables so that such outgoing mail gets signed

If you had both x.y.com and y.com configured here, x.y.com mail would not get DKIM-signed.

if a domain has a catch-all or domain alias then we no longer force the creation of postmaster@ and so we should not be checking for its existence in the status checks

see 85a40da8

status checks: if a service isn't available publicly, check if it is available on the loopback interface to distinguish not running from not accessible

Add additional options to really prevent apt from asking questions, which causes setup to hang because stdin/out have been redirected.

fixes #270, #291

fixes #308

cc333b39 worked for fresh systems, but if the system already had the daemon running the api.key file would already exist and the test would pass to early. Now removing the file first.

fixes #322
