Re: autoresponding to Yahoo DMARC breakage

The most "sane" out-of-mind response should only be sent *if* the out-of-mind person is named explicitly as a recipient in the RFC822 To: header. Anything To: somelist@somehost does not qualify :)
This highly effective trick was in the procmail example vacation script in 1991, and doubtless goes back much farther than that. It's a little dismaying to hear that there are still people writing autoresponders who don't know about it.
