I also run my own mail server. I had to firewall off Google's MXes for this exact reason: silent and not-so-silent email rejection when offered over IPv6.
I run my own mail server and have no trouble at all delivering mail to Gmail over IPv6. I do have SPF, DKIM, DNSSEC and DANE on my mail servers. My DMARC policy is p=none. If it matters, the MTA is a heavily hacked version of qmail. While I believe that Gmail rejects some people's mail, every time when I have looked in detail, I have found that their mail authentication isn't working properly. I'd suggest starting there.
