I get errors when trying to send emails, and the header of the email shows me that ip 158.69.9.104 (Zoho) was not found or is in trouble.
I did a dns test here, and it accuses error too:
Error encountered:
IP DNS [135.84.80.196] is not properly configured
I'm having several different clients with shipping issues, I'm just screwing one, but I have others with the same problem.
