Gmail (thus Nanog) rejecting ipv6 email

Sun Apr 3 17:50:06 UTC 2022

i try to keep a list of goog's ipv6 email space and don't deliver to it;
rather using ipv4 instead.  unfortunately, goog does not cooperate with
dnswl.org, so this can not be automated.

this is mildly damaging to the ipv6 religion, but i don't let that spoil
my coffee.

their lack of cooperation with the dns good list means inbound from them
gets dropped when one of their outbound smtp senders gets badlisted,
which they often do.  i do not let that spoil my coffee either.

i would not want to work for goog's email service; too much pain.
