Re: [xwiki-devs] [xwiki-users] Lots of disabled Yahoo email addresses on the xwiki.org lists
This is partially XWiki's infrastructure fault, too. 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 On 11/02/2016 07:57 AM, Vincent Massol wrote:
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:
<[email protected]>: 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 -Vincent

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>@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 On 11/07/2016 09:24 AM, Sergiu Dumitriu wrote:

By the way, all of Pascal's and Julio's emails (and other yahoo users) end up in my spam folder because of the broken DKIM signatures. On 11/07/2016 09:24 AM, Sergiu Dumitriu wrote:
