Gmail throttling?

some of our users have forwarded the email to Gmail and Gmail now are  
complaining that this is bulk mail and delaying it.

We have SPF, DKIM, DMARC, even SRS to try these things do not happen :(

Anyone know if there is any new policy in Gmail about that?

Above all, the message refers to a non-existent URI!
