My email provider ZOHO is not recognizing the IP address of MX1, which should be 18.104.22.168, as for as I can tell. This is diff from MX2 and MX3 ( 22.214.171.124 and 126.96.36.199) . Are these the current IPs?
I apologize, but I'm not familiar with Zoho's email services or MX Records. If you are having trouble configuration your domain name to work with those email services/MX Records, you may want to contact their support to ensure that they are correct. Perhaps another community member that is familiar with their services will be able to offer some suggestions. ^Gary
