I neglected to even think about the full circle DNS which is for outgoing mail. The issue here is that the server's IP address has no rDNS PTR record at all. The authority for this is rackspace, so they would need to install a PTR from 201.228.239.104.in-addr.arpa. (i.e.rDNS for 104.239.228.201) to mail.mailman3.org. Probably infrastructure@python.org can help with this.
I pinged Donald off line; this should be set up now.
