This is just about the quickest turnaround I've ever had.
It appears the problem is on their side, not mine. dig
tell us that.  According to Reto Lichtensteiger
% dig mx cms.ca
; <<>> DiG 2.2 <<>> mx cms.ca 
;; res options: init recurs defnam dnsrch
;; got answer:

                       ^^^^^^^^^^^^^^^^^^^^^^^^
;; QUESTIONS:
;;      cms.ca, type = MX, class = IN
;; AUTHORITY RECORDS:
ca.     43200   SOA     relay.cdnnet.ca. hostmaster.relay.cdnnet.ca. (
                        199707180       ; serial
                        21600   ; refresh (6 hours)
                        900     ; retry (15 mins)
                        604800  ; expire (7 days)
                        43200 ) ; minimum (12 hours)
There is a "Start of Authority" record for the cms.ca domain, but they
haven't defined any MX (Mail eXchanger) -or- A records for the domain, so
there's no way to deliver mail to that domain.
