Step by step in IONOS

Verify your domain

Your email provider needs proof that you control this domain before it accepts email for it.

Type
TXT
Host name
Leave this field empty
Value
Copy it from Zoho Mail Admin Console (see below)

Where to find your value

In the Zoho Mail Admin Console (mailadmin.zoho.com) open Domains, select your domain and go to Verify Domain Ownership. Choose TXT from the drop-down to see your value.

It looks like: zoho-verification=zb followed by a unique code and .zmverify.zoho.

Set up DKIM

DKIM signs your mail so receivers can trust it. How DKIM works

Type
TXT
Host name
<selector>._domainkey
Value
Copy it from Zoho Mail Admin Console (see below)

Host name: The selector is the name you type when adding DKIM in Zoho. Zoho's example is zoho, which gives the host zoho._domainkey.

Where to find your value

In the Zoho Mail Admin Console go to Domains, select your domain, open the Email Configuration tab and select DKIM. Click Add, enter a selector, choose a 1024 or 2048-bit key, and copy the TXT value.

  • After the record is published, click Verify for the selector in Zoho, then enable DKIM.

Add the DMARC record (recommended)

DMARC tells receivers what to do with mail that fakes your domain. How DMARC works

Type
TXT
Host name
_dmarc
Value
v=DMARC1; p=none; rua=mailto:dmarc@yourdomain.com
  • Roll out in phases: p=none (reports only), then p=quarantine, then p=reject, raising pct gradually.

Check your setup

Once the records are saved, run a live check. We look up your domain in public DNS and tell you what is right, missing or wrong, with the fix in IONOS’s words.

We only read public DNS records. Nothing is stored.

Common mistakes with Zoho Mail on IONOS

Using US MX values for a non-US account

The MX domain ending changes with your Zoho data center. If you signed up in the EU, India or another region, copy the values from your Admin Console.

Keeping old MX records with a low number

Records from a previous provider with equal or higher priority (such as 0 or 5) can stop mail reaching Zoho. Delete them.

IONOS: CNAME records go on their own subdomain

IONOS supports only one top-level CNAME record, so each CNAME is created by first adding a subdomain and then giving it an Alias.

IONOS: MX and a top-level Autodiscover CNAME can't coexist

IONOS doesn't allow a domain to have both an MX record and a top-level Autodiscover CNAME. Microsoft's guide uses the subdomain method above for Autodiscover.
