Summary

You cannot send emails to specific domains in Hosted Email Security (HES). The mail tracking logs display the following message:

Recipient domain not found.

Details

The error happens because the domain name of the recipient may be invalid or could not be resolved by HES DNS servers.

Make sure the recipient's domain has a valid A and MX record. To check if the recipient's domain has a valid A and MX record, you may run nslookup or use a third-party tool such as MX Toolbox.
