gitlab DMARC configuration issue

postfix is rejecting e-mails from GitLab most likely due to a GitLab.com DMARC configuration issue. I am not experiencing any other e-mail deliverblity issues. So I think the issue on the GitLab side. I could disable DMARC verification but that's besides the point.

Did you recently change from gitlab.com to mg.gitlab.com?
