Forgot to mention the second component of DMARC, SPF, which is also
partially broken by XWiki's infrastructure. The problem with SPF is that
mails for <someone>(a)xwiki.org are forwarded by xwiki.org to xwiki.com
(gmail.com in reality), and this forwarding isn't allowed by a strictly
configured SPF domain. There's no easy fix for this, the only solution
would be to replace self-hosted mailing lists with Google Groups, so
that xwiki.org also becomes an alias for gmail.com

DMARC doesn't work well with mailing lists, since they tend to break
DKIM signatures. The only way to fix the problem (at least for the
majority of emails) is to remove the footer from the configuration.
So, options:
- remove the footer, which means that "incompetent" users will have a
hard time finding information about unsubscribing, but allows users from
modern email providers to subscribe
- keep the footer, which makes it harder for legitimate users to stay
subscribed

Hi everyone,
Just to let you know that on the 28th of October, there were 234 members of the xwiki
users list who’ve been automatically disabled (ie they’re not going to receive mails).
This is apparently caused by a change in Yahoo’s email policy:
<gumush(a)gmail.com>om>: host gmail-smtp-in.l.google.com[74.125.133.27] said:
550-5.7.1 Unauthenticated email from yahoo.com.br is not accepted due to
550-5.7.1 domain's DMARC policy. Please contact the administrator of
550-5.7.1 yahoo.com.br domain if this was a legitimate mail. Please visit
550-5.7.1 https://support.google.com/mail/answer/2451690 to learn about
the 550 5.7.1 DMARC initiative. o3si17254181wjx.109 - gsmtp (in reply to
end of DATA command)
So if you’re in that case, please contact Yahoo as mentioned in the message above.
Thanks
