The failings here only occur when there is DNS issues at example.org /
example.com

And looking at the answer section from dig:

dig example.org

;; ANSWER SECTION:
example.org.		33350	IN	A	93.184.216.34

dig example.com

;; ANSWER SECTION:
example.com.		86400	IN	A	93.184.216.34

They resolve to the same place so using one of the other may not give us
peace of mind - we just have to cope with their DNS being down / broken
once in a while.

The official documentation at https://www.iana.org/domains/reserved
mentions that these are the proper domains to use for this purpose, it
says:

IANA-managed Reserved Domains

Certain domains are set aside, and nominally registered to “IANA”, for
specific policy or technical purposes.

Example domains

As described in RFC 2606 and RFC 6761, a number of domains such as
example.com and example.org are maintained for documentation purposes.
These domains may be used as illustrative examples in documents without
prior coordination with us.

Title:
  Behat: example.org is unreliable for anti-spam

Status in Mahara:
  Expired

Bug description:
  This feature is failing on the main branch.

  ./mahara_behat.sh rundebug settings/register_configuration.feature

  And I press "Register"
  And I should be on "/register.php"
  And I should see "You have successfully [...snip...] processed."
        The text "You have successfully [...snip...] processed." was not found anywhere in the text of the current page.

  I added a breakpoint and took a look at the page.  The form does
  report the attached error, and the content of the form looks okay. The
  error doesn't indicate which field is the issue either.

  I tried adding a second institution and selecting that just in case.
  It didn't change the outcome.

  Further investigation has tracked this to the anti-spam we use.  Turns
  out the domain 'example.org' may not be the best to test against.

  On htdocs/lib/antispam/AdvancedSpamTrap.php line 35 we check the
  validity of the domain name by checking for MX, A, and AAAA records.
  This was my local results:

  gold@shipnet:~/Mahara/codereview/test/behat ((baa775acad...)) $ php -a
  Interactive mode enabled

  php > $domain = 'example.org';
  php > echo (checkdnsrr($domain, 'MX'))?'Y':'N';
  N
  php > echo (checkdnsrr($domain, 'A'))?'Y':'N';
  N
  php > echo (checkdnsrr($domain, 'AAAA'))?'Y':'N';
  N
  php > $domain = 'example.com';
  php > echo (checkdnsrr($domain, 'MX'))?'Y':'N';
  N
  php > echo (checkdnsrr($domain, 'A'))?'Y':'N';
  Y
  php > echo (checkdnsrr($domain, 'AAAA'))?'Y':'N';
  N
  php >

  At this point I would be inclined to be swapping out instances of
  `example.org` for `example.com` (or at least another domain we can
  rely on) in the behat tests.
