You can add https://emailsrvr.com/ -> Rackspace to that list.

E-mail is about transparency but as long as the mailop reaches out to
D Telekom and identifies themselves and gives them private contact
information, that they could add ​to their own private database, I
don't see the need to make this info public.

Think this thread went on a tangent, regarding the use of an 'imprint'

(And yes, spammers are using sites with JUST the imprint as 
justification to remove their IP/domain)

But ANYONE who uses a domain in their PTR record, that doesn't point
to 
their company website, where contact information can be found on the 
operator, will suffer a hit to their reputation.  Wasn't this on a 
M3AAWG Best Practices document?

eg..

secureserver.net
serverdata.net
ppe-hosted.com
cloudfilter.net
hostedemail.com
hwclouds-dns.com
antispamcloud.com
mktomail.com

.. you can't 'white label' , email is about transparency.
