If you have previously configured the anti - spam connection filtering in your Exchange 2003 environment
and you are migrating to Exchange Server 2007, you can take advantage of a new tool now available
from Microsoft that migrates your list of allow/deny addresses, block list providers, blocked senders,
and domains. You can download the tool from the following link: microsoft.com/downloads/

Content Filtering
This feature filters junk email by a method that learns what is and what is not spam. This agent filters all
messages that come through all Receive Connectors on the server. It is not a best practice, however, to
filter messages from trusted partners or from inside the Exchange organization to reduce the chance of
false positives. The contents of the message are constantly scanned for specific words or phrases and
over time what constitutes spam can be easily determined.
