Make Zoho Mail DMARC-compliant
How to authenticate Zoho Mail as a sender on your domain - so its mail passes SPF, DKIM and DMARC, and you can safely reach enforcement.
Three steps to authenticate Zoho Mail
Zoho Mail needs to pass SPF and DKIM, and align with your domain so DMARC passes. Here’s how – confirm the exact values against Zoho Mail’s current documentation as you go.
Add Zoho Mail to your SPF record
SPF lists the services allowed to send as your domain. Add Zoho Mail’s include to your existing SPF record – don’t create a second SPF record, merge it into the one you have.
Watch the 10-lookup limit: every include counts, and going over makes SPF fail silently. Hosted SPF keeps you safely under it automatically.
Add this mechanism to your SPF record
include:zoho.com
Turn on DKIM signing
DKIM cryptographically signs each message so receivers can prove it really came from you and wasn’t tampered with. In the Zoho Mail admin console (Email Configuration -> DKIM), enable DKIM and publish the selector TXT record it provides.
DKIM is what keeps you authenticated even when a message is forwarded – so it’s worth getting right. More on how DKIM works →
- Enable DKIM inside Zoho Mail
- Publish the DNS records it gives you
- Wait for it to verify, then send a test
Confirm alignment, then enforce
With SPF and DKIM set up, check that Zoho Mail aligns – that the authenticated domain matches your visible From address. Once every legitimate sender aligns, you can move DMARC to p=reject safely.
DMARCER’s enforcement journey shows you exactly when it’s safe to advance – no guesswork.
Good to know
Use the include for your Zoho data region - include:zoho.com, include:zoho.eu or include:zoho.in. Confirm yours in the Zoho admin console.
