; Add these lines:
$ORIGIN 204.161.209.IN-ADDR.ARPA.
$TTL 86400
; Change (your) line above to:
@ IN SOA ns.octopusmarketing.com. cngo.emaylme.com. (
; see the difference?

; I'm going to have to guess what the *actual* nubmer you are using

1.204.161.209.IN-ADDR.ARPA. IN PTR mail.investimmo.ca.
2.204.161.209.IN-ADDR.ARPA. IN PTR mail.adjointeplus.ca.
193.204.161.209.IN-ADDR.ARPA. IN PTR ns.octopusmarketing.com.

Is your NET block this big? 209.161.204.1 - 209.161.204.193 and beyond?
I only used 1 and 2 for your mail servers based on the fact they were
already used. Now that I created a working IN-ADDR.ARPA. zone for you.
You can adjust the mail IP's if I guessed their IP's wrong. You can not
use 193.204.161.209.IN-ADDR.ARPA. as a RR because there are no
other addresses within it. The IN-ADDR.ARPA. zone indicates your NET block.
It starts on the NET number and ends on the BCAST. This is why I had to
chop the 193.204.161.209.IN-ADDR.ARPA. file off to 204.161.209.IN-ADDR.ARPA.
So that you can define the NET block *within* the zone. Otherwise, everything
would be *outside* the zone - which is why you had this problem.
Hope this clears things up.
Best wishes,
Chris
