Emails are not received after setting up a company on Proofpoint Essentials
Inbound email fails after initial setup
Items to check:
- Verify that MX records for the registered domain have been updated. You can validate domains using the “Test Domain” option on the Domains page.
- Check external resources for propagation issues.
- Proofpoint Essentials MTAs are updated every 30 minutes. Therefore new domains (or changes to existing domains) may not have been applied.
- Ensure you have added the correct IP ranges to lock down your firewall to allow Proofpoint to connect to your mail server.
