Use the method he http://www.outlook-tips.net/howto/rules.htm - use .ru

That appears to be for a whole domain. I want to filter on the country suffix,
not just the domain.

ie. ALL domains from Russia, the Netherlands, etc. to be filtered on.

format, not just ru to reduce the risk of false positives. But I prefer to
do it by charset (to get what the junk filter for domains misses) - look for
words in the header and use the words that identify the charset.

That's another way. Unfortunately I can't figure out how to view the headers.
Outlook doesn't make it easy to do even the simplest things for those such as
myself who aren't rocket scientists.

I'll keep on looking.
