This typically means:
Your MX records point to Zoho Mail.
Some users may use Google Workspace (Gmail) for specific accounts or departments.
You may have email routing set up to forward or dual-deliver emails to Gmail.
External sender sends an email to user@yourdomain.com
.
The domain's MX records point to Zoho, so:
Email hits Zoho Mail servers first.
Based on your routing or forwarding setup in Zoho:
If the recipient is a Zoho user, the email is delivered to their Zoho Inbox.
If the recipient is a Gmail user (hybrid account):
Zoho forwards the email to Gmail (user@yourdomain.com
on Google).
Google receives it and places it in the Gmail inbox.
User sends email from Zoho interface.
Zoho handles the outbound delivery directly to the recipient's server.
Gmail user sends email from Gmail interface.
Google handles outbound SMTP delivery to external recipient.
SPF, DKIM, and DMARC should be properly configured for both Zoho and Google to avoid delivery issues.
Zoho user sends email to another user who is on Gmail:
Zoho delivers mail to Google (via SMTP).
Gmail user sends mail to a Zoho user:
Gmail routes it to Zoho via domain’s MX (unless internal routing rule is in place).
