I didn't know anyone still cared? Google has been trying to move away from Internet email for many years now. Just let them. There is no way you can "fix" that problem on your side. If you care about specific recipients, then inform them that Google randomly throws away some of their legitimate

V4 via V6 and IGP routing protocols

Periodically I still do some work on routing protocols. 12? years ago I had kind of given up on ospf and isis, and picked the babel protocol as an IGP for meshy networks because I felt link-state had gone as far as it could and somehow unifying BGP DV with an IGP that was also DV (distance vector)

I'm actually not here to start a debate... happy to learn that the v4 over v6 feature I'm playing with actually exists in another protocol, mainly.
