      "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."
