This genuinely confuses me. I have used every dmarc/dkim test out there that I can find, without paying money, and every one of them I pass. When I send email to my gmail account it passes.

 

But when I send email to this group, I get half a dozen failures and complaints... what gives?

 

PS google dislikes your email,
