I&#x27;ll tell you what I want: I want Google to help identify non-DKIM-compliant forwarders. As the operator of (yes, I know) a vanity e-mail domain with DKIM, SPF, and DMARC records, I have no problem sending mail to gmail directly; in fact, my outgoing mail uses postmark, so I&#x27;m not even directly responsible for my sending reputation.<p>BUT! It drives me crazy that many of my recipients get e-mail at hosts (schools, mostly) that forward the e-mail 
with differences (encoding changes, subject changes, etc.) that invalidate the DKIM signature. Since they&#x27;re forwards, the SPF check is going to fail, too, so the end result is that google shoves it into a spam folder.<p>I claim that google definitely has the data to be able to identify these bad forwarders--heck, even mail sent <i>from gmail</i> to these hosts will presumably fail DKIM checks on the way back into google--and I&#x27;d love to see them contact these domains, or even publish a list of known bad forwarders, so that I can push them to make changes.
