Gmail (thus Nanog) rejecting ipv6 email

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 email. Send a paper mail
or phone them if necessary.  That's pretty much all you can do.  If
those recipients continue to use gmail, then that's their decision and
problem.

I assume NANOG is informed about this now.
