Copy that to Reply-To: and write a mangled From: that looks troopy
but passes DMARC. Just like MLMs do.
Lists at MLMs have names that the subscribers will recognize, but the
scout troop only has the Yahoo address.
There are certainly kludges that one can apply to circumvent DMARC
rejections, but this is a clear failure, an existing legitimate mail
use that DMARC breaks.
The entire problem with catering to the long tail is that it is holding
hostage better email security. We should stop doing that. There is no
right to stasis forevermore. If the scouts email breaks, they can get
somebody to fix it. They will thank us in the long run when scammers
can't phish using them as a prop.
