We currently use GWS and due to legacy practices, we cannot migrate away from it. Not easily anyway. The issue we have is that while we have Zoho Mail, we get duplicate copies of emails.

Our setup is that GWS is our primary. We have Zoho MX records in DNS alongside our GWS, but Zoho MX servers are lower priority. We have SPF DMARC and DKIM all configured, but the co-existence with GWS is painful because we receive duplicate copies, sometimes 3 or 4, in Zoho Mail.

Anyone had this issue?
