This is apparently caused by a change in Yahoo’s email policy: <gumush@gmail.com>: 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 _______________________________________________ users mailing list users@xwiki.org http://lists.xwiki.org/mailman/listinfo/users
