Using 3rd party
software
The
anti-spam features in Exchange 2003 are
far from complete, and using software
like Policy Patrol and others is still
recommended, but for small businesses or
companies that cannot afford these
products - Exchange Server 2003 can now
handle most the job, especially with IMF
around.
However, there are still
many
problematic "features" (as Microsoft
likes to call them) in the built-in
anti-spam support in Exchange 2003. One
bad thing about the Exchange Server 2003
Spam protection options is the fact that
there is no GUI-easy way to import or
export blocked e-mail addresses or
sending domains.
Another
bad thing is that there is no default
way to see if the filters are working,
and how much spam is blocked.
To
configure e-mail blocking do the
following:
-
Go to
the properties of the Message
Delivery settings.
-
Click
new to add a connection filter.
-
Add
the desired RBL service and click
OK.
-
You
can also configure exceptions for
these rules. Click the Exceptions
button and enter your settings.
-
A
warning shows that you have to
enable the filtering at the SMTP
virtual servers.
-
Go to
the properties of your SMTP Virtual
Server.
-
On the
General tab, click the Advanced
Button.
-
Click
the Edit button.
-
Check
the 'Apply Connection Filter'
checkbox.
-
Click
Ok all the way out.
