yahoo.com has already been doing this for a while, now gmail.com is
doing it too :(
In addition to the link you quoted:

here's another one:
https://wiki.list.org/DOC/What%20can%20I%20do%20about%20members%20being%20unsubscribed%20by%20bounces%20of%20Yahoo%20user's%20posts%20for%20DMARC%20policy%20reasons%3F
The problem is that the mailman instance running the cygwin mailing
list (and ALL lists hosted by sourceware, for that matter) needs to
be reconfigured to cope with stricter DMARC rules. I'm not an admin,
so you will need to redirect this request to the postmaster that
manages cygwin's mailman instance.
In the meantime, the only "workaround" is to subscribe to the list
using an address that isn't quite as nasty about DMARC rules. It's
sad that more and more sites are clamping down, but that's the price
we pay for spammers.
I recently ran into the same problem sending to a KDE list. In my
case, I was using a sourceforge.net FROM: address, but actually sending
through my ISP (frontier.com). Sourceforge had the DMARC policy that
mail claiming to be from sourceforge.net should not be accepted if it
came from anywhere else. I think the final solution was for them to
drop that rule, since at least one of the uses of sourceforge is
exactly that type of aliasing. I don't think gmail will do the same.
You are using a gmail.com address, but it looks like you might have
sent it from vanav.org. In this case, I suspect your only solution
will be to actually send mail from gmail.com using the gmail.com smtp
server.
Eric's suggestion to resubscribe from an address at a site which is
less strict about DMARC rules would work, but I think the underlying
issue will arise again, as long as you use an smtp server other than
the one from the From: address you are using.
