Configuring IMF
Configuring Intelligent
Message Filter involves two settings:
Gateway Blocking
Configuration - In Gateway Blocking
Configuration, you establish a threshold
based on a spam confidence level (SCL)
rating above which the gateway server
takes action on the message. You also
define the type of action you want the
gateway to take.
Store Junk E-mail
Configuration - In Store Junk E-mail
Configuration, you define the thresholds
based on an SCL rating that Microsoft
Exchange 2003 mailbox stores use to
determine whether to deliver messages to
a user's Inbox or Junk E-mail folder.
In order to configure IMF
follow these steps:
-
Open the Exchange
System Manager snap-in (ESM).
-
Expand your
Organization object, expand Global
Settings. Right-click Message
Delivery and choose Properties.
-
Notice there is a new
tab named "Intelligent Message
Filtering". Click on it.
-
In the Gateway
Blocking Configuration section enter
the number you chose, based upon
your own preferences. I use 7, but
you may want to experiment with
lower or higher numbers. Selecting a
lower number for the SCL rating
filters more messages, but also
increases the likelihood of false
positives, which are legitimate
messages that appear to be UCE.
Selecting a higher number for the
SCL rating filters fewer messages,
but also reduces the likelihood of
false positives.
-
Now choose the action
to perform when blocking messages.
You can select Archive
-
In the Store Junk
E-mail Configuration select your
desired threshold. I use 5. but
again, you may want to experiment
with lower or higher numbers.
-
Click Ok.
After you configure
Intelligent Message Filter, you must
enable this filter on all inbound
gateway SMTP virtual servers. |
