Filtering SPAM by domain suffix

[Art Frankel]

Does anyone know how to add Junk Senders in Outlook 2003
so that it will match on just the last part of the domain
name.

For example:

".us" will block "(e-mail address removed)"
and "(e-mail address removed)"

2003 seems to only let you add FQDN and will not work
with entries like "*.us".

2002 used to work with entries like ".us", ".biz" and
such.

Thanks!
