Zoho Mail Not Receiving Emails: Diagnostic Table

When Zoho Mail not receiving emails hits your team, match the symptom to the likely fix before changing anything:

Most zoho mail incoming mail issue cases sit in the first three rows. For broader problems such as login or sending, see our Zoho Mail not working guide.

Fix 1: Zoho Mail MX Records and Priority

Zoho's Configure Email Delivery page says you will receive emails only if MX records are set correctly. Its reference values are:

Zoho says the MX domain ending changes with the data centre that hosts your account, so India-hosted accounts use the .in hosts. Always copy the exact values from Admin Console > Tools & Configurations, which shows the records for your domain.

• Delete old MX records. Zoho says that if other MX entries have a lower priority value, such as 0 or 5, emails will not reach Zoho Mail.
• Turn off local email delivery at your old web host. Otherwise mail sent from that server is delivered internally and never reaches Zoho.
• No priority field? Make sure mx.zoho has the lowest priority value of the three.
• Wait for DNS. Zoho notes changes can take 12-24 hours, depending on TTL. Use the lowest TTL your provider allows.

Zoho suggests an MX lookup with its free Toolkit to confirm what the world sees. Wrong zoho mail mx records cause more zoho mail not receiving emails cases than anything else. After any change, send a test from an outside address such as a personal mailbox and confirm it lands.

Fix 2: Confirm Domain Verification

Zoho's Domain Verification help lists four methods: one-click, TXT, CNAME or HTML. If the domain is not verified, finish this before anything else, because an unverified domain is a common reason for Zoho Mail not receiving emails on a new setup. Zoho suggests deleting the verification TXT record after success.

Fix 3: SPF, DKIM and DMARC

These records mainly protect the email you send, but they also affect what you receive. They rarely explain Zoho Mail not receiving emails on their own, so check them after MX:

• SPF. Zoho's SPF help gives v=spf1 include:zohomail.com -all, or v=spf1 include:one.zoho.com -all if you use several Zoho services. Remove includes for services you no longer use.
• DKIM. Per the DKIM help, add a selector in the Admin Console, publish the TXT value it generates, then click Verify.
• DMARC. The DMARC help lets you generate a TXT record from the Admin Console.
• Incoming checks. Organisation spam control lets admins decide what happens to incoming emails that fail SPF, DKIM or DMARC. A strict setting can push a sender's mail to spam or quarantine.

Fix 4: Check Filters

Zoho's Filters help says every incoming and outgoing email is processed by your filters. A rule like "move to folder" can make it look like Zoho Mail is not receiving emails when they are simply filed elsewhere. Open Settings > Filters, review each rule and edit or delete the culprit. Use Run Through Filter to re-sort a folder after fixing it.

A quick test: search all folders for a missing message. If it turns up, the problem was never Zoho Mail not receiving emails; it was a filter.

Fix 5: Spam Folder and Quarantine

Check the user's Spam folder first. Then, as an admin, open the Spam Quarantine section. Zoho lists incoming emails held for validation errors, organisation blocklists or Zoho blocklists there. Admins can deliver or deny each one, set up notifications, and assign self-moderators who approve their own quarantined mail.

If one sender keeps getting held, add them to the Allowed List rather than turning off spam checks for everyone. Quarantine is the second most common cause of Zoho Mail not receiving emails from one sender.

Fix 6: Blocked Senders and Rejected Lists

Zoho's Spam Control Lists help explains that a blocked sender can be marked as spam, quarantined, rejected with a bounce, or rejected silently. The Rejected List blocks all incoming email to specific internal addresses. Users also have their own Allowed, Blocked, Trusted and Rejected lists, per the user settings help.

A silent reject is the hardest case: the sender sees no bounce and you see nothing. Check every list for the missing sender or domain. When Zoho Mail not receiving emails affects only one partner company, a blocked domain is a likely cause.

Fix 7: Mailbox Storage

Zoho's Blocked Accounts help lists exceeding the mailbox storage limit among the reasons an account can be blocked. In the Admin Console, the Users section has a Storage view showing what each user has used. Free up space, add storage or upgrade the plan, then check Security & Compliance > Blocked Accounts and unblock the user if needed. If Zoho Mail not receiving emails affects only one heavy user, check storage before anything else.

Fix 8: User Status and Plan

If one address bounces, check that the user is active and has a plan assigned. When a user is made inactive, Zoho's user settings help says the admin can choose to block incoming emails, which then bounce back to senders. Blocked users and groups also stop receiving until unblocked.

Reactivate the user, or move the address to an active user as an alias if the person has left. This is the usual answer when Zoho Mail not receiving emails is limited to a former employee's address.

Fix 9: Forwarding, POP and IMAP

• Forwarding. Zoho's Email Forwarding help has a "Delete original email copy after forwarding" option. If ticked, emails leave Zoho Mail. Admin-set forwarding is only on paid plans.
• POP. The POP help says emails are downloaded and deleted from the server unless "Keep a copy on the server" is set. A desktop client can quietly empty the web inbox.
• IMAP. Use the server details on Zoho's IMAP help page, and update old client settings after switching providers.
• Free plan. Zoho's pricing page says the Forever Free plan does not include IMAP, POP or ActiveSync, so a phone app on that plan can look like Zoho Mail not receiving emails.

Zoho Mail Pricing in India

If storage or POP and IMAP access is behind Zoho Mail not receiving emails, the plan matters. These INR prices come from Zoho's official pricing data for its Zoho Mail pricing page, excluding GST:

Zoho says the free plan is available only in select data centres. Upgrading only helps when storage or protocol access is the real cause of Zoho Mail not receiving emails. Read our guide to whether Zoho Mail is free.
