running spamassassin-3.1.0 I hoped to filter messages on the basis of non-english subject line so went looking in the files spama uses. I see something about FOREIGN language but then it dawned on me, being horribly colloquial, not to mention near illiterate, how FOREIGN is totally subjective.
For my usage, anything that is not in english is spam. Maybe not techniquely in some far fetched case but still something I cannot use. Any one have examples of a spama filter based on that?
