Hi there Carlos -
The main reason people say you should have both is that many customers do
things completely legitimately (like mail forwarding) that break SPF. Any
of those messages that lack DKIM will automatically fail DMARC, and
customers will wonder what the heck happened to their mail,
While I can't speak for everyone, in theory yes, they could impact your
reputation if those are a significant % of your traffic to us. Of course,
if they are a significant % of your traffic, you're probably not sending
much mail to us in the first place, so... *shrug*.
However, I would make the
At AOL we see this as well, and for now we're treating it as "they're still
figuring this DMARC thing out". If it's someone we have a regular
relationship with and it's not a blip, we'll reach out and ask what's up.
If it appears to be a serious issue - a domain getting heavily abused for
example
I'll second what Franck has said -
Once we we figured out all of the 3rd parties we needed to talk to,
virtually everyone was happy to work with us to find a solution. The
biggest problem we've had, by far, was internals who couldn't be bothered
to figure out how mail works, and then suddenly
this parked domain.

Yes, mainly for brand/domain protection. We see spammers co-opt domains all
the time that are widely recognized but not normally used for mail. I've
told people in the past to do this for domains that they own that should
never send mail, especially lookalike or spoof domains that you own for
Sorry for not saying so earlier, but we're looking into the multiple to
thing. We'll roll out a fix asap.

At AOL we're doing this with a confirmation popup in clients we control and
then sending a unsubscribe mail on behalf of the user when we find
unsubscribe mailto links, and I know that some 3rd party clients also have
started to implement unsubscribe logic (iOS 10 does so for example). I also
know
This is a pretty common practice for domains that people own for brand
protection as well - a0l.com has a -all SPF, p=reject DMARC policy, and no
MX.

1) Yes, via two methods - The first is mailbox aggregation (why setup
forwarding when I can just read the mailbox for you?) which is currently
supported by a number of email providers. The second is via Authenticated
Received Chain (ARC - see http://arc-spec.org/). Also currently supported
