Analyzes the content of 
messages using the Intelligent 
Message Filter (IMF), which 
is based on Microsoft’s 
SmartScreen content filtering 
technology. The technology 
reviews the content of the mes-
sage and rejects content from 
fraudulent links and spoofed 
domains. The technology also 
provides a certain level of anti-
phishing protection.

Combines the results of the con-
tent, connection, sender/recipi-
ent, sender reputation, sender 
ID verification, and Outlook 
e-mail postmark validation to 
create an overall spam assess-
ment. The result of this check 
determines the action Exchange 
Server takes on the message. 
The administrator can configure 
various actions based on any of 
these criteria.

Controls the rate at which 
Exchange Server sends and 
receives messages. The use of 
message throttling for incom-
ing messages helps prevent 
Distributed Denial of Service 
(DDoS) attacks. Checking for 
message sending patterns helps 
reduce the probability of a direc-
tory harvesting attack.
