Good afternoon Deb, If you are using Microsoft Outlook,
you can have the unwanted senders mail sent directly to
the trash once received. In Outlook, click on Organize
icon, on your tool bar, select Junk email. Then use the
pull down menus to set the rules to Move Junk messages to
Deleted Items, and then click the Turn on Button.
Then go back to your un-wanted mail and right click on it
and select the Junk email list, add to junk senders list.
You will receive a confirmation, just click ok and you are
finished. No new software needed. You can also do this
using Netscape, just a differant setup is all. Hope this
helped.

Have a great day.
Dave
