Or just turn off remote email forwarding..

I think forwarders and mailing lists should start rewriting From:

list or forwarding adress, To: replaced with forwarding final
destination, and Subject: replaced with "Fwd: [Original subject]".
That should make it DMARC safe, even with strict alignment enabled.

Any chance you'll be using ARC headers to mitigate the damage to mailing
lists and other forwarders?
