Understanding IP Reputation

Trend Micro Email Security offers two tiers of protection. Connection-based filtering at the MTA connection level, including IP reputation-based filtering provided by Trend Micro Email Reputation Services (ERS), is the first tier. The second is content-based filtering at the message level.

Trend Micro Email Security makes use of Trend Micro Email Reputation Services (ERS) Standard Service and Advanced Service. Email Reputation Services use a standard IP reputation database and an advanced, dynamic IP reputation database (a database updated in real time). These databases have distinct entries, allowing Trend Micro to maintain a very efficient and effective system that can quickly respond to new sources of spam.

Configure the following settings on the Settings tab of the IP Reputation screen:

• Quick IP List, which is also known as dynamic IP reputation settings, controls how Trend Micro Email Security uses the dynamic IP reputation database from Email Reputation Services Advanced Service.

• Standard IP Reputation Settings control how Trend Micro Email Security uses the standard IP reputation database from Email Reputation Services Standard Service.
