I consider it to be an absolute requirement for any autoresponder to not
reply to a message that isn't addressed to the recipient it is acting on
behalf of. Anything else is just begging for the sort of exponential
autoresponder meltdown that's happened on some mailing lists in the past
(most notably faq-maintainers).

Yup. Very annoying, but necessary. Otherwise, you'll end up sending
autoreplies to mailing list traffic, which is an absolute no-no even if
the mailing list isn't "properly" tagging messages with a Precedence
header.
