Email from Oooma not recieved

Post by e_n » Tue Aug 25, 2020 4:51 am

Does anyone have a support email address for Ooma? I am not receiving service-related emails from them. I think it is due to mis-configured DNS on their end, and my email server is rejecting them. Here is a sample from my email server log:

Code: Select all

Here's the results of DNS lookups for the relevant domain name/IP address - As you can see, the sending domain is not found, although reverse lookup does work:

Code: Select all

root@mailserver:~$ nslookup
> o1.vip.wpforms.com
Server:		X.X.X.X
Address:	X.X.X.X#53

** server can't find o1.vip.wpforms.com: NXDOMAIN
> 167.89.98.220
220.98.89.167.in-addr.arpa	name = o1.vip.wpforms.com.

I'd like to try sending this in rather than chatting/calling as it's not really about phone service.
