I think this would be a good time to fix your mail server setup.
You're never going to get much v6 mail delivered without rDNS, because
receivers won't even look at your mail to see if it's authenticated.

CenturyLink is reasonably technically clued so it shouldn't be
impossible to get them to fix it.


Nothing wrong with my mail server setup, except the lack of RDNS. 
Lacking reverse should be one of many things to consider with rejecting 
e-mails, but should not be the only condition.

everyone else should change instead."

Don't hold your breath.
