Configuring DNS MX Records Parent topic

After configuring Cloud Pre-Filter settings and verifying that email traffic is delivered from Cloud Pre-Filter to IMSVA, add the Cloud Pre-Filter "Inbound Server Address" to the MX records for your DNS server. The Cloud Pre-Filter host displays under the Inbound Server Address section of the Domain tab. This is the final step before using Cloud Pre-Filter to scan your email traffic.

WARNING
You MUST configure your mail delivery (MX) records to route your email traffic through Cloud Pre-Filter. If this step is not completed, your messages will be delivered to your local servers, and not to Cloud Pre-Filter for scanning.

Trend Micro recommends configuring the MX records for Cloud Pre-Filter with a higher priority (specify a lower number) than your existing MX records. Your existing MX records then act as a backup to Cloud Pre-Filter.
