Related to Bug 1229640 we only need a few subdomains to remain active, and these can be CNAMEd to their thunderbird.net counterparts. They are: live.mozillamessaging.com -> live.thunderbird.net broker-live.mozillamessaging.com -> broker.thunderbird.net mx-live.mozillamessaging.com -> mx.thunderbird.net autoconfig-live.mozillamessaging.com -> autoconfig.thunderbird.net support.live.mozillamessaging.com and support.mozillamessaging.com are used in-product and thus need to remain active redirects for the foreseeable future, unfortunately.
Webops, please do *not* act on this bug at this time. We need to complete additional work on our side, and making these CNAME changes prior to that work will break production.
We should ship this in the same window as bug 1341798.
