Junk Mail
Outlook
2003 has a built in Junk Mail folder. Suspicious email is
sent there automatically.
Microsoft
provides several options for filtering. One of the safest is to
create "white lists" of the friends, family, and businesses
you know. The
"black list" would contain senders you want to block.
When the
email comes into the Inbox, you can Add the Sender to the Safe
List, or Add the Sender to the Blocked List.
