Not Calontir, not your fault, Yahoo's Fault.

   "The problem for mailing lists isn't limited to the Yahoo subscribers.
   Since Yahoo mail provokes bounces from lots of other mail systems,
   innocent subscribers at Gmail, Hotmail, etc. not only won't get Yahoo
   subscribers' messages, but all those bounces are likely to bounce
   them off the lists.  A few years back we had a similar problem due
   to an overstrict   implementation of DKIM ADSP, but in this
   case, DMARC is doing what Yahoo is telling it to do."
