Since most spam comes from .ru .ca and thousands of other spoofed email addresses I figure I can block everything else except the main ones. Therefore how can I block all domains except .net .com .org and .edu?
There has to be a "block all but XX" addresses.
I am using
Windows 2003 Server Standard
Exchange 2003 Standard
McAfee Groupshield 6 for Exchange
