[TriLUG] Spamassassin to filter non-US

[Amnon]

>From the days when we used spamassassin, in the local.cf file:

#
header   FROM_FOREIGN_DOMAINS   From =~ 
/\@.*\.(?:at|au|be|br|cc|ch|cl|cn|cz|de|dk|fr|fi|hu|it|jp|kr|lv|mn|nl|no|nz|pl|ro|ru|se|sh|tr|tw|tv|za)\>/i
describe FROM_FOREIGN_DOMAINS   Domain is foreign address
score    FROM_FOREIGN_DOMAINS   1.0
#
header   FROM_FOREIGN_DOMAIN5   From =~ /\@.*\.(?:ru)\>/i
describe FROM_FOREIGN_DOMAIN5   ru Domain is foreign address
score    FROM_FOREIGN_DOMAIN5   3.0
#

Add your own countries.
