Troubleshooting Incoming Email Issues in cPanel/Webmail Print

✨ Introduction

Receiving emails is crucial for communication, and when issues arise, it can be frustrating. Incoming email issues in cPanel/Webmail can be caused by incorrect email configurations, quota limits, DNS problems, or server-side restrictions. This comprehensive guide will walk you through step-by-step troubleshooting techniques to identify, debug, and resolve issues efficiently. ✅

🔍 1. Verify Email Client & IMAP/POP3 Settings ⚙️

One of the most common reasons for incoming email failures is incorrect email settings. Double-check:

✅ Incoming Mail Server: Ensure you are using the correct IMAP/POP3 server (e.g., mail.yourdomain.com).
✅ IMAP vs. POP3:

• IMAP (Port 993 for SSL/TLS, 143 for STARTTLS) - Recommended for multi-device access.

• POP3 (Port 995 for SSL/TLS, 110 for STARTTLS) - Downloads emails to one device. ✅ Authentication: Ensure authentication is enabled for incoming emails.
  ✅ Correct Credentials: Use the full email address as the username and the correct password.

📌 Find Recommended Settings: In cPanel → Email Accounts → Connect Devices or Configure Mail Client.

📨 2. Test Receiving Emails via Webmail ✉️

If your email client is not receiving emails, check if Webmail works:

✅ Login to cPanel → Email Accounts → Webmail (Roundcube, Horde, SquirrelMail).
✅ Send a test email to your own address and check if it appears in Webmail.
✅ If emails appear in Webmail but not in your email client, the issue is likely with the client settings or local network.

🔹 Solution: Reconfigure your email client with the correct settings or try a different mail application.

📊 3. Check Email Storage Quota 📈

Emails may not arrive if your mailbox is full.

✅ Go to cPanel → Email Accounts and check your storage usage.
✅ If your mailbox is full, either delete old emails or increase the storage quota.
✅ Empty the Spam & Trash folders to free up space.

📂 4. Review Email Logs for Clues 📝

If you have server access, checking logs can help diagnose incoming email failures.

📌 Log Locations for Exim (cPanel Default Mail Server):

/var/log/exim_mainlog  # Main email transactions log
/var/log/exim_rejectlog  # Rejected emails log
/var/log/exim_paniclog  # Critical email errors

🔹 Look for error messages like 550, 451, or 421 to identify the issue.

👨‍💻 No Root Access? Contact your hosting provider to review the logs for you.

⚡ 5. Check Email Services (IMAP, POP3, Exim) & Server Status 🔄

Your mail services must be running properly for emails to be received.

📌 Check if mail services are running (For Root Users):

service exim status  # For Exim (Mail Transfer Agent)
service dovecot status  # For IMAP/POP3

If they are not running, restart them:

service exim restart
service dovecot restart

✅ No root access? Contact your hosting provider.

🌐 6. Verify DNS & MX Records 🔧

Incorrect DNS or MX records can cause emails to be undelivered.

✅ Use tools like MxToolbox or DNSChecker to verify MX records.
✅ Ensure your MX records are correctly set, e.g.:

example.com MX 10 mail.example.com

✅ Check SPF & DMARC records for proper authentication.

🔹 Solution: If DNS records are incorrect, update them in your domain registrar's dashboard or cPanel’s Zone Editor.

🚫 7. Check Sender’s Email Service & Spam Filtering 🛑

The issue could be on the sender’s end. Ask them to:

✅ Ensure their email is not blacklisted.
✅ Verify that their SMTP server is working correctly.
✅ Check if their email is marked as spam by your server’s filters.

📌 Look in Webmail’s Spam folder to see if emails are being flagged incorrectly.
