Description
Account
The Cloud Pre-Filter account is used to manage Cloud Pre-Filter policies. You must create one Cloud Pre-Filter account before you use the Cloud Pre-Filter service.

Policy
Cloud Pre-Filter policies apply to your domains. You can create only one policy per domain. When the messages sent to the domain reach Cloud Pre-Filter, Cloud Pre-Filter uses the policy for that domain to determine how to scan the messages and how to route the messages to the domain.
Cloud Pre-Filter rejects all messages to domains that do not exist in the Cloud Pre-Filter policy list.
Cloud Pre-Filter service stores all policies in the cloud.
Inbound Server
Inbound servers of Cloud Pre-Filter are the servers that receive your inbound messages. Cloud Pre-Filter provides the inbound server addresses when you create a domain to change your MX records.
