I find this excerpt from cygwin-help a bit confusing. Notice the
"yahoo.com" in the "Remote host said:" message. What's really going on
here? Why is yahoo.com doing the authentication for a gmail.com address?

I haven't looked at the details of this particular error, but are you
using an alias'd address? For example, my return address here is
@users.sourceforge.net. However, they only resend mail to that address
to my real address @frontier.com. I have validated to frontier.com
that I really do own the address @sourcegforge.net. So I send through
the frontier server with a From: address of sourceforge.
In my case, with a KDE mailing list, when KDE gets a message, they ask
the domain of the message (sourceforge) about their policy. Recently,
they upped the level, and so told KDE to reject any mail appearing to
be from sourceforge if it didn't actually come from their. Thus I got
lots of this type of error. Someone finally convinced sourceforge that
didn't make sense, since one of their offerings is aliased email
addresses, which were then all bouncing.
So, your From: is gmail. Are you actually sending through a gmail
server, or through a yahoo server? (Note yahoo servers handle all
sorts of other domains, not lease most of the domains used by AT&T as
an ISP.)

No, I have the cygsimple address directly enrolled. In fact on this
list if you use a forwarding address like users.sourceforge.net you'll
need to also register the primary address that address resolves to.

Reading and understanding email bounces is notoriously hard.
I got the same email, just with my email address instead of yours. The problem is not related to the recipient's address, but to the sender's address. A quick query to <cygwin-get.205832@cygwin.com> got me the original message that bounced. Its headers follow.

What happens is that ezmlm (the mailing list software) broadcasts this message (after adding a bunch of links at the bottom) to everyone subscribed, but with the sender unchanged. Yahoo has got a DMARC policy set up that is supposed to ensure that only Yahoo servers can send messages marked as "from ...@yahoo.com". As you can see, Google is enforcing the policy and correctly rejecting the message as fake (it really wasn't sent by Yahoo, but by Sourceware). This is only going to happen more and more often as email providers up the battle against spam.
The best solution is to change the way ezmlm re-sends the messages, I bet there's a big discussion about it somewhere on the Internet.

Probably hundreds if not thousands of such discussions!
Who is in charge of the list server configuration? Sourceware itself, or
someone from Cygwin?

Indeed. The problem is, I have no idea what this is about. If you have
problems in terms of the sourceware mailer stuff, please feel free to
politely explain what the problem is and ask if that can be fixed on
either the overseers AT sourceware DOT org mailing list, or the Freenode
IRC channel #overseers.
Thanks,
Corinna

Overseers,
See the description below of a problem that is occurring because of
DMARC rules in place by yahoo.com. Is there anything you can do for this?
