Incomplete DMARC mangling on the list (was: Re: The spiped Docker image)

I noticed that the 'From' of Vijay's email was mangled by the list in
response to, what I assume, DMARC records on the sending domain. However
the DKIM-Signature was not stripped and fails to validate (because of
the mangled 'From'):

> Authentication-Results: chrono.xqk7.com;
> 	dkim=fail reason="signature verification failed" (2048-bit key; unprotected) header.d=yahoo.com header.i=@yahoo.com header.b="q8zkdFPX";
> 	dkim-atps=neutral

I assume that this is not intended behavior.
