Ergo, facilitating heuristics is bad?

I'm not following the logic, but it must just be me. I don't see how or why facilitating heuristics is bad -- for email, source IP addresses, Subject line content, mismatched rfc821.from/rfc822.from, body content ("Viagra", image/jpg, image/gif), are all useful as input to a heuristic function.

I believe you're arguing that the sole purpose of duplicating header information is to facilitate heuristics for use by a SpamAssassin-like function, and that such duplication of header information has no other purpose. Is that correct?

1. I think it's dandy for spamassassin to use heuristtics. In fact, I think it's essential. However, I made a distinction between software using heuristics, vs. standards.

2. I took Justin's note as providing encouragement to have the standard duplicate headers, because it would facilitate some heuristics.

So,

Having this be a justification for duplication of data is very much a case of having mailsig participate in the use of heuristics, even though the mailsig spec, itself, would not contain heuristics.
