These are IPs used by millions(?) of users that apparently have been
abused by enough to warrant the above to penalize them, but the
alternative is either having to welcomelist the sender or somehow
remove the IP locally from being checked. Both options are only
after they've been blocked at least once. And this is only one
Google IP - how many others could there be?
Ideas greatly appreciated.

avoiding checking google ranges in DNS*Ls could make sense, at least we'd
avoid excessive DNS requests towards them and getting blocked there.
however the only SA way I can think of is adding
209.85.128.0/17 and 74.125.0.0/16 to trusted_networks which would result
into ALL_TRUSTED hitting.
