We have Exchange 5.5, Sp4 on a WinNT server. Can I block/reject an outside email address from coming in to any of our companies email accounts? For example, if a hacker sends a virus in an email to several employees can I block the email address in the Microsoft Exchange Administrator console somehow? I know it is possible to do indivually with the Outlook client application by making a rule but I would like to be able to do it using Exchange Server App.
Thanks,
