I wonder what'll happen with this one...
Your DKIM now looks more sane. And the MUUG server reports that it's passing with flying colors. So it must just be a gmail thing.
When diagnosing these things, I use yahoomail as it lets you drill down and see exactly what checks are failing. gmail might give you a similar way to see what's going on in its web interface. Send your gmail/yahoomail another test email Drill down into the headers and see if all the DKIM / SPF / DMARC / whoknowswhatelse stuff is passing.
Oh ya, gmail in their take-over-the-world wisdom have a proprietary anti-spam system in place now that might solve this gmail-spam problem. Search google-site-verification and sign up and put their record in your DNS TXT (in addition to your SPF record... so you'll have 2+ separate records). Weird, the main google-site-verification site doesn't seem to mention the anti-spam usage, but I know for one of my clients (big email sender) we required this verification to stop always going into spam boxes.
Needless to say, this unilateral non-RFC garbage from google is further proof they are the devil.
