an example is the domain al-muqeet.com

if you query the MX record for such a domain you get back

;; QUESTION SECTION:
;al-muqeet.com.                 IN      MX

;; ANSWER SECTION:
al-muqeet.com.          900     IN      MX      0
localhost.al-muqeet.com.

;; ADDITIONAL SECTION:
localhost.al-muqeet.com. 867    IN      A       127.0.0.1

now, such a record should be considered INVALID
