Solving Common Email Connection Errors
If your Outlook, Apple Mail, or Gmail app is showing errors like "Connection timed out" or "Server not found," follow this troubleshooting checklist to restore your email functionality.
1. Verify Your Settings (The Golden Rule)
Most errors are simply typos in configuration. Ensure your mail client uses these standard Jiinubi settings:
- Incoming/Outgoing Server: mail.yourdomain.com (replace with your actual domain)
- Username: Your full email address (e.g., info@yourdomain.com)
- Password: The password you set in cPanel (test via Jiinubi Webmail)
- Authentication: Must be enabled for the Outgoing (SMTP) server
2. Check Your Ports and Encryption
Some ISPs block standard email ports (like 25) to prevent spam. Use these secure ports instead:
| Protocol | Secure Port (SSL/TLS) | Recommended? |
|---|---|---|
| IMAP (Incoming) | 993 | Yes (syncs across devices) |
| POP3 (Incoming) | 995 | No (downloads to one device) |
| SMTP (Outgoing) | 465 | Yes (SSL) |
3. Common Error Messages & Solutions
- "Outlook cannot connect to your outgoing (SMTP) server":
- Cause: Port 25 is blocked by your network or ISP.
- Fix: Change SMTP port to 465 with SSL/TLS or 587 with STARTTLS.
- "Mailbox is Full / Quota Exceeded":
- Cause: Storage limit reached for that email account.
- Fix: Log in to cPanel > Email Accounts > Manage. Increase storage or delete old emails from Sent/Trash.
- "Relaying Denied" or "Authentication Required":
- Cause: Sending mail without authenticating to the server.
- Fix: Enable "My outgoing server (SMTP) requires authentication" and use the same credentials as incoming mail.
4. Is Your IP Blocked?
Entering the wrong password multiple times (usually 5+) can temporarily block your IP to prevent brute force attacks.
- Symptom: Cannot access website, cPanel, or email from current Wi-Fi but works on mobile data.
- Fix: Find your IP (search "What is my IP") and submit a support ticket to whitelist it.
5. Troubleshooting via Webmail
If unsure whether the problem is server-related or your device:
- Test Webmail: Go to https://yourdomain.com/webmail and log in.
- If Webmail works: server is fine, issue is in your app settings.
- If Webmail fails: there may be a server issue or your account is suspended.
Tip:
Always double-check your email address and password in the client app before changing server settings.
Warning:
Changing ports or authentication settings incorrectly may temporarily block email access. If unsure, contact support first.
