Andy,

It is purely up to the receiver to set PolicyOverrideType because it IS based 
on local policy and thus up to the individual receiver.

Thanks Mike
It's not my domain, I just noticed it in my spam..
Ah I just found the XML Schema for reports, was about to ask if there was a 
specific list then found PolicyOverrideType

It's starting to make more sense now. Is it purely up to the receiver to set 
the PolicyOverrideType based on local policy?

Andy,

I you can find the record for this message in your aggregate report, check for 
the presence of a <reason><type> tag.  If that is present and the type is 
either "forwarded" or "mailing_list" it will tell you that the receiver 
overrode the reject policy for that reason. It's not necessarily specific to 
Google, any receiver can do it and be within the bounds of the DMARC spec.

The pct tag is set to 100.
I would speculate it *is* directly related to DMARC as the message shown in 
Gmail is "Our systems couldn't verify that this message was really sent by 
junc.eu<http://junc.eu/>"

Hopefully someone from Google can chime in here

Gmail is on this list so I'll let them answer for themselves.  Were I to 
speculate, there could be any of several reasons in addition to your two ideas, 
including:

It passed DMARC but their content classifiers still called it spam, and they 
acted accordingly.

You have a "pct" tag, DMARC failed, and the "upgrade" process described in 
Section 7.1 has been applied.

What does disposition mean in this case?
It also raises the question, why did Gmail put the email in spam instead of 
rejecting it as the dmarc policy specifes?
I can think of 2 reasonable things:
1: Google is still not confident senders are implementing dmarc correctly and 
as a precaution quarantining messages (instead of rejecting them)
2: Gmail is smart enough to take into account the presence of the List-Id 
header and/or other headers and applying special case processing for mailing 
lists.

Any thoughts?

Has anyone else noticed Google are now inserting a dmarc result into their AR?
I just noticed this from an email Benny sent (which ended up in spam due to 
p=reject)
