Ok, could you please copy/paste here the content of an email without hostnames?
You might have a problem with your notification emails sent, as I suspect hostnames should actually be available. You might open a ticket with Technical Support for further analysis.
By the way, I checked if there is a way to get a scheduled report showing out-of-date clients. You can basically achieve it following these steps:
- Go to Reports > Quick Reports
- Select "Computer Status" and "Client Inventory Details"
- Click on Advanced Settings
- Select "older than the last 30 days" in "Definition Date" drop-down list
- Use other filtering options if needed
- Save the filter using the button available at the right-bottom corner
- Go to Scheduled Reports
- Create new Scheduled Reports, with "Computer Status" and "Client Inventory Details" selected. Also choose your saved filter
- Configure proper email addresses and scheduling
- Save it
