Remember that we're in the Microsoft era. I just checked -- Netscape 4.0+ will filter on body, but not arbitrary headers -- it's subject/sender/body/priority/date/status/to/CC/to or CC/age in days or nothing.
Incorrect. If you select "Message Filters..."
then select "New..."
The select "Advanced..."
You can add any type of header information to filter against in Netscape. I do it all the time. I don't use Outlook so I can't speak to it.
