To ensure your organization achieves effective email security protection, Trend Micro Email Security recommends you perform the following tasks after data migration:

  1. Verify migrated policy data under Inbound Protection and Outbound Protection.
    1. Go to the following locations respectively:

      • Virus Scan

      • Spam Filtering

      • Content Filtering > Content Policy

      • Data Loss Prevention > Data Loss Prevention (DLP) Policy

      Note:

      After migration, policy rules are categorized into the following four types: virus scan, spam filtering, content filtering, and DLP.

    2. Select Error or Warning from the Migration status drop-down list.
    3. Follow the on-screen instructions in the Migration Status column to fix error settings or confirm warning settings and enable the corresponding policies.
    4. Reorder policy rules.

      You can manually reorder the policy rules in each domain after migration if they do not meet your requirements. For details, see Reordering Policy Rules.

  2. Verify other migrated data.
    1. Go to Inbound Protection > Connection Filtering > IP Reputation > Settings to verify email reputation settings.
    2. Go to the following locations respectively to verify approved and blocked IP addresses:

      • Inbound Protection > Connection Filtering > IP Reputation > Approved IP Addresses

      • Inbound Protection > Connection Filtering > IP Reputation > Blocked IP Addresses

    3. Go to Inbound Protection > Domain-based Authentication > DomainKeys Identified Mail (DKIM) Verification to verify the Global DKIM Enforcement rule.
    4. Go to Inbound Protection > Domain-based Authentication > Domain-based Message Authentication, Reporting and Conformance (DMARC) to verify DMARC settings.
    5. Go to Inbound Protection > Spam Filtering > Time-of-Click Protection to verify time-of-click protection settings.
    6. Go to Outbound Protection > Domain-based Authentication > DomainKeys Identified Mail (DKIM) Signing to verify DKIM signature settings.
    7. Go to Administration > Policy Objects to verify policy object settings.
