Email Troubleshooting

When email stops working, the fastest fix comes from naming the symptom first: mail will not send, mail does not arrive, a bounce comes back, messages land in spam, or webmail will not open. Each has its own causes and its own detailed guide. This page is the starting point: it helps you find which problem you have, checks the settings everyone should confirm first, and sends you to the right guide.

1. Start here: match your symptom

Write down the exact error message before you change anything. It usually tells you which of these you have.

2. Check which email service you have

Domain India offers email in two different ways, and their settings are not the same.

Not sure which one you have? Read Business Email vs the email included with your hosting, or ask support with your domain name. Business Email users should go straight to setting up Outlook, Apple Mail and your phone for Business Email and Business Email sending limits.

3. Confirm the basic settings

Compare your mail app with this table. These ports were measured as open on our shared servers on 20 September 2026.

Three points cause most failures:

• The username is the full address, [email protected], not just you.
• The password is the mailbox password, not your control panel or client area password.
• Port 26 is closed on every Domain India server, so older guides that suggest it no longer work. Port 25 is often blocked by internet providers; use 465.

If mail.yourdomain.com gives a certificate warning, do not click past it. In cPanel, Email › Email Accounts › Connect Devices shows the exact server name for your account. The full port list is in Domain India web hosting port numbers.

4. Mail will not send

When receiving works but sending fails, the mailbox itself is almost always fine. Work through these in order:

The complete guide, including suspended accounts and full disks, is I can receive mail but I cannot send it.

5. Mail is not arriving

Check these in order before assuming mail was lost:

• The Spam or Junk folder, in webmail as well as in your app. Webmail always shows what is really on the server.
• The mailbox quota. A full mailbox refuses new mail and the sender gets a bounce. Free space or raise the quota as described in managing your email accounts.
• The domain's MX record. It must point to the server that holds your mailboxes. If you recently moved your DNS or your website, the MX record may now point somewhere else.
• Forwarders and filters that move mail to another address or folder.
• A suspended hosting account, for example with an unpaid renewal invoice. Mail stops in both directions. Check your service under Services and any open invoices.

The detailed checks are in troubleshooting email not receiving.

6. A bounce message came back

A bounce is the receiving server explaining why it refused your mail. Look for two things in it: the status code (a 4xx code is a temporary problem that may retry; a 5xx code is permanent) and the plain-language reason, such as "mailbox full", "user unknown" or a mention of SPF or DMARC.

Understanding email bouncebacks decodes the common messages one by one and says what to do for each. Keep the full bounce, including its headers, if you plan to contact support.

7. Mail goes to spam, or your server is on a blocklist

When your messages leave your Sent folder but land in the recipient's spam folder, the problem is usually with your domain's authentication records, not your mail app.

In cPanel, Email Deliverability shows whether SPF and DKIM are valid for each domain and offers the correct records. Copy the records it gives you rather than typing an example from a guide. If you also send through a newsletter tool, a CRM or Google Workspace, that service must be included in the same single SPF record.

Read SPF, DKIM and DMARC for setup, and email blacklist removal if a bounce names a blocklist.

8. Sending limits on shared hosting

Shared hosting limits how much mail one account can send, so a single compromised script or a bulk mailing cannot damage the reputation of the server everyone else relies on. We measured these limits on our servers on 22 September 2026:

Mail from webmail, from mail apps and from website scripts such as contact forms and WooCommerce order emails all counts towards the same limit. Everyday business mail stays well inside it. Newsletters and bulk campaigns do not, and they should go through a dedicated email delivery service instead. See do you limit the amount of mail I can send per hour.

Hitting the limit without sending bulk mail is a warning sign: a hacked contact form or a stolen password may be sending spam in your name. Change the mailbox passwords and ask support to check the account.

9. Webmail will not open

Webmail needs only a browser, so it also tells you whether a problem is in your mail app or in the mailbox.

There is no webmail.yourdomain.com on DirectAdmin or Webuzo. Sign in with the full email address and the mailbox password. If the page does not load on one network but does on mobile data, your IP address may be blocked (see section 4). Clearing the browser cache or trying a private window fixes most login loops. Full steps: how to log in to webmail.

10. Where Domain India products fit

Every cPanel, DirectAdmin and Webuzo hosting plan includes email accounts at your domain, managed in the same panel as your website.

If you want email that keeps running independently of your website, or you do not host your website with us, Business Email is priced per mailbox and starts with one. It includes DKIM signing on every message and SPF and DMARC records for your domain.

Prices on the cards are Domain India list prices and exclude 18% GST.

11. When to contact support

On shared hosting the mail service is managed for the whole server, so you cannot read its logs or restart it, and you do not need to: we check the logs for your address. If you run your own mail server on a VPS, start with troubleshooting SMTP relay issues in VPS hosting.

Contact us when the settings in section 3 are right and the matching guide has not solved it. Live chat runs 24/7, and tickets get a first response within 15 minutes; a fix can take longer depending on the problem. We do not offer phone support. Include:

• the email address that has the problem;
• the mail app and device, and the server, port and encryption it uses;
• the exact error message, or the full bounce;
• what you have already tried, and your public IP address if you cannot connect at all.
