_And_ I can't be certain about openstack.org, but for dns-operations my "spidey sense" combined with the mail headers: X-Original-To: [email protected] Delivered-To: [email protected] along with lists.dns-oarc.net. 30 IN CNAME mail.dns-oarc.net. tell me not to expect a separate MX record for lists.dns-oarc.net. All that said, everybody else pointed out the appropriate RFCs etc. On 5/27/14, 7:38 PM, hua peng wrote: > Are you sure?
