IP Filtering Service Parent topic

The IP Filtering service has two individual components: Email Reputation and IP Profiler.
  • Email reputation filters connections from spam senders when establishing SMTP sessions.
  • IP Profiler helps protect the mail server from attacks with smart profiles from the Intrusion Detection Service (IDS).

Trend Micro recommends deploying IP Filtering as the first line of defense in your messaging infrastructure.
Although most email systems have a multi-layer structure that often includes some pre-existing IP blocking, spam filtering, and virus filtering, Trend Micro recommends completely removing other IP blocking techniques from the messaging environment. IP Filtering should act as the precursor to any application filtering you might use.

Note
IP Filtering is only available from IPv4 networks. Incoming email messages from IPv6 networks are not blocked by Email Reputation or IP Profiler.
