Oh I see. Thanks.
So to use mail's Header terminology, only the Return-path: is modified, 
not the From:

Is this related to DMARC in general?
May be not corrected by SRS, because of DMARC is more recent than SRS…

Or this is a yahoo challenging with a somewhat too strong configuration?
I mean, did they configure to specifically check the From: header?
