Sender Filtering (IP Profiler and Email reputation) blocks connections at the IP level.
IP Profiler uses your customized settings for email messages that signify different
types of attacks. Email reputation uses information from the Trend Micro Threat
Reputation Network to determine if the computer initiating an SMTP connection is a
known
sender of spam.
If Sender Filtering (IP Profiler or Email reputation) is used together with the Sendmail
MTA, additional configurations must be done to ensure that Sendmail uses FoxLib and
therefore gets the real IP address of the SMTP client contacting FoxProxy.
This section describes the procedures for configuring FoxLib on Red Hat 6 and 7 to
support Sendmail and Sender Filtering.
