Hi, Some of our community members reported problems while sending email to mailings hosted by Ceph project. We reported the problem to the host company and it's happening because some changes on DNS records done some time ago, and they're working to fix it. The issue happens to all mailings (except ceph-devel which is hosted by vger.kernel.org) and a workaround is to update the mail address from <mailing>@ceph.com to <mailing>@lists.ceph.com. The email addresses are also documented on our website: https://ceph.com/irc/#mailing-lists Kindest regards, Leo -- Leonardo Vaz Ceph Community Manager Open Source and Standards Team -- To unsubscribe from this list: send the line "unsubscribe ceph-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
