Yahoo breaks every mailing list in the world including the IETF's

http://j.mp/1e68Xlm  (IETF / John Levine)

   "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."
