HES verifies the IP/FQDN that you entered when adding a domain to its current MX record. This process is called “sanity checking”. To manually check if the IP address is matched to your current MX record:
- Open a command prompt window.
Type the following command, then press Enter.
nslookup –q=mx <domain name>

The results will show the IP address for that specific MX record. You may use this IP address to add your domain on the HES console.
If the MX record for the domain you are trying to add is pointed to the HES servers (this information can be found in your welcome email), do one of the following options:
Option 1: Revert your original MX record since HES will not accept your domain activation request.
Option 2: Create a secondary MX record with a different priority and point it directly to your mail server.DNS propagation takes 24-48 hours globally; please wait for the MX record to be propagated before trying to add the domain again.
