Why don't you properly configure DKIM and SPF? Then you won't have this problem.

From the fine article he linked: SPF, DKIM and DMARC are all domain verification systems for validating e-mail’s origin to prevent spam. I have all three records set in DNS records for all the domains I send e-mail from, verified they were correct using testing tools, and I still get flagged as spam.
