ns.realtime.com seems to be running :
;;      version.bind, type = TXT, class = CHAOS
VERSION.BIND.           0S CHAOS TXT    "8.3.2-T1B"

( and that version should not have problems with this mx, however there
is two problems ; both mailservers
;; ANSWER SECTION:
caroldochenrealtors.com.  1H IN MX  10 mail.caroldochenrealtors.com.
caroldochenrealtors.com.  1H IN MX  20 mail.mintecommerce.com.

are CNAME's , which is if not forbidden it's at least stupid 
;; ANSWER SECTION:
mail.caroldochenrealtors.com.  1H IN CNAME  caroldochenrealtors.com.
caroldochenrealtors.com.  1H IN A  64.105.113.114
;; ANSWER SECTION:
mail.mintecommerce.com.  1H IN CNAME  mintecommerce.com.
mintecommerce.com.      1H IN A         64.105.113.115
mintecommerce.com.      1H IN A         64.105.113.114

Again, bind-8 should not have problems with this.
