most mailing lists break spf, they send email on your behalf
from an ip that is not in your spf record
most mailing lists break dkim because they modify headers, therefore the
DKIM-Signature, even the list may add a signature on top of yours
ARC helps with that, i dunno if mailman supports it
>The forwarded emails do not come from me so fails DKIM/DMARC
when A forwards to B C's email, the from is rewriten to match A, email
lists "forward" emails but keep the From intact

>> 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!
MAC addresses are local to your network segment (your provider
datacenter) there is no way google knows them.
are you sure tor and your smtp aren't using the same IPv6
>I don't think its you Tor node - it just google. I note that your DMARC, SPF, etc are set and valid. You mail server is not an open relay. I maintain a few mail servers and run into these types of problems. There is no real reason for them. Microsoft is the worst - no logic what so ever.
since this is already off-topic for -relays, i want to spam about an email
