Cloud Pre-Filter has no impact on how IMSVA should be deployed.
Note
Note
Cloud Pre-Filter uses port 9000 as the web service listening port. This port must be open on the firewall for IMSVA to connect to Cloud Pre-Filter.
However, when adding Cloud Pre-Filter policies you must change the MX records, of the domain specified in the policy, to that of the Cloud Pre-Filter inbound addresses. The address is provided on the bottom of Cloud Pre-Filter Policy List screen. Click Cloud Pre-Filter in the IMSVA management console to display the Cloud Pre-Filter Policy List screen.
Tip
Tip
Trend Micro recommends adding IMSVA’s address to the domain’s MX records, and placing IMSVA at a lower priority than Cloud Pre-Filter. This allows IMSVA to provide email service continuity as a backup to Cloud Pre-Filter.
