Relative hostnames have a fall-back lookup with the machine's hostname appended, which makes no sense. Add a period, e.g. "my.hostname.com" => "my.hostname.com.", to prevent that.
This caused false positive Spamhaus checks. Fixes#185.
This seemed to already be technically supported but the validation is now stricter and the admin is more helpful:
* Postfix seems to allow @domain.tld as an alias destination address but only if it is the only destination address (see the virtual man page).
* Allow @domain.tld if it is the whole destination address string.
* Otherwise, do not allow email addresses without local parts in the destination.
* In the admin, add a third tab for making it clear how to add a domain alias.
closes#265
* also fixes the footer alignment to be within a container rather than a container-fluid
* this changed the width of the login form slightly, so am cleaning that up too
see #244
The problem was that custom records defined for a subdomain where implicit
records are otherwise defined (e.g. A/AAAA records for the root) were ignored.
Though additional_records for a subdomain are processed in the base call to
build_zone (the call for the parent domain), and so custom records that don't
override implicits were working fine, those that overrode implicits were
ignored.
This was because the recursive call to build_zone for the subdomain creates the
implicit records (including A/AAAA records for the root), and so by relying on
the base call to add the additional_records fails because has_rec returned
true.
Adding a subdomain's additional_records in the child call works because has_rec
returns false when testing whether to add an e.g. A/AAAA override for the root,
as the defaults have not yet been added.
* If the PRIMARY_HOSTNAME is in a zone with a DS record set at the registrar, show any DNSSEC failure (but only a failure) immediately since it is probably the cause of other DNS errors displayed later.
* For zones, if a DS record is set at the register, do the DNSSEC test first because even the NS test will fail if DNSSEC is improperly configure.
* But if a DS record is not set, the this is just a suggestion to configure DNSSEC so offer the suggestion last --- after mail and web checks.
