Re: [exim] SPAM Filtering - Losing the war!

The point here is *false* positives, and whether the
decision about whether something should be treated as spam
should be up to the addressee, or up to some MTA
administrator exercising a technical prejudice.

Argument by analogy is usually futile, but in your terms
this would be like the postman discarding, say, letters
where the postmark wasn't completely legible or where he
didn't like the way the letterhead was formatted. Actual
postal authorities (in reasonable countries at least)
prohibit that sort of interference.
