What’s New

  • Stricter enforcement for unverified domains and inbound server configuration
    Trend Vision One Cloud Email Gateway Protection and Trend Micro Email Security now enforce stricter validation for domain configuration to help prevent delivery issues and improve mail flow security. Emails sent to or received from new unverified domains will be rejected. Emails sent to new domains without inbound servers configured will also be rejected. Administrators must verify all domains and configure inbound servers to ensure uninterrupted inbound and outbound email delivery.
