Configuring Cloud Pre-Filter<br />

Suggested IMSVA Settings When Using Cloud<br />

Pre-Filter<br />

Cloud Pre-Filter uses port 9000 as the web service listening port. This port must be<br />

open on the firewall for IMSVA to connect to Cloud Pre-Filter.<br />

While Cloud Pre-Filter does not impact the deployment of IMSVA, Cloud Pre-Filter<br />

does impact how you should configure IMSVA.<br />

TABLE 8-2. IMSVA Recommended Settings When Using Cloud Pre-Filter<br />

SECURITY SERVICE RECOMMENDED ACTION<br />

IP Filtering<br />

<br />

(both Email Reputation<br />

and IP Profiler)<br />

When Cloud Pre-Filter filters email messages for all<br />

your domains:<br />

Disable or do not activate IP Filtering<br />

Cloud Pre-Filter uses Email Reputation to filter all<br />

email messages before the messages reach your network.<br />

This makes using IP Filtering (both Email Reputation<br />

and IP Profiler) redundant.<br />

When Cloud Pre-Filter filters email messages for<br />

some of your domains:<br />

Enable and use IP Filtering (both Email Reputation<br />

and IP Profiler)<br />

Cloud Pre-Filter is not using Email Reputation to<br />

scan all email messages before the messages reach<br />

your network. The messages from domains that are<br />

not routed through Cloud Pre-Filter may still be malicious.<br />
