Secret Google and Microsoft Blacklists affecting non tor IPs if on same server.
Just had to shut down my exit temporally while Google sorts out their secret blacklisting system on my innocent non-tor IP.
My server has two IPs, not consecutive. One I use for my own email server and public web server, locked tight and private. No relays, no proxy. This IP is not on any blacklist.
Second IP is used for TOR alone and forced exit is via this second IP, and only has TOR-use ports open. This IP is not on any blacklist other than being listed as a tor exit.
Torrc config has careful port selection, not port 80 except to a single /8 block. 443 open etc. Despite many other ports open, apart from the obvious at risk ones which are blocked, I have had no abuse notices over last year it has been up. Quiet ISP. ISP have no idea as to why Google blocked my IP (despite high traffic from second IP!).
Alas it seems that both Google now and Microsoft before tar both IPs with the same brush and reject. Google just stared blocking emails from my domain to all gmail accounts It is a real performance finding out who to contact to undo this block. Microsoft was a pain last year, but this year is it is Google. Google’s own postmaster tools reports no issues about my domain! Alas:

Really annoying that my email server IP has never sent anything, no relay, no spam, almost no traffic so what is stated is not true and even their own tools reports nothing.
Is Google looking at MAC addresses to do this? How can we stop it? I really do not want to run another server just for tor as that costs!
