Understanding Email Synchronization

Email account synchronization ensures your messages, folders, and status (read/unread, sent, deleted, etc.) are consistent across devices and platforms (mobile, desktop, webmail). If synchronization fails, you may see missing emails, unsent messages, or inconsistent folders.

Step 1: Basic Checks Before Troubleshooting

Before diving into specifics, check the following:

  • Internet Connection: Ensure your device is online.
  • Correct Password: Verify you are using the latest password for your mailbox.
  • Account Status: Confirm your hosting account is active and not suspended.
  • Storage Limits: Make sure your mailbox is not full.

Step 2: Verifying Your Email Settings

Double-check your email client (Outlook, Apple Mail, Thunderbird, mobile apps) is configured with the correct settings.

Recommended IMAP Settings:

Incoming Server (IMAP): mail.enmail.co
Port: 993
Encryption: SSL/TLS
Username: your full email address
Password: your mailbox password

Recommended SMTP Settings:

Outgoing Server (SMTP): mail.enmail.co
Port: 465
Encryption: SSL/TLS
Username: your full email address
Password: your mailbox password

> Tip: Always use your full email address as the username and ensure "Require authentication" is enabled for outgoing mail.

Step 3: Common Sync Errors and How to Fix Them

A. Authentication Errors

Symptoms:

  • "Login failed"
  • "Username or password incorrect"
  • Emails not syncing; prompts to re-enter password

Solutions:

  1. Re-enter your email address (ensure spelling and case are correct).
  2. Reset your mailbox password via the Email Control Panel in your client area.
  3. Remove and re-add the account in your email client if issues persist.

B. Server Connection Issues

Symptoms:

  • "Cannot connect to server"
  • "Connection timed out"
  • Server not responding

Solutions:

  1. Check for typos in server address (mail.enmail.co) and port numbers.
  2. Ensure SSL/TLS is enabled.
  3. Try connecting via Webmail to confirm server is accessible:
    • Go to: https://webmail.enmail.co
  4. If using public Wi-Fi or corporate networks, try a different network—some networks block email ports.

C. Folder/IMAP Sync Problems

Symptoms:

  • Sent, Drafts, or custom folders not syncing
  • Only Inbox appears; other folders missing

Solutions:

  1. In your email client, ensure IMAP (not POP3) is selected during setup.
  2. Re-subscribe to folders:
    • In most clients, right-click the account/folder list and choose “Subscribe” or “IMAP folders.”
  3. Refresh folder list or restart the email client.

Example (Outlook):

  • Go to Send/Receive > Update Folder List
  • Right-click the account > IMAP Folders > Query > Subscribe to missing folders

D. Mailbox Quota or Storage Full

Symptoms:

  • "Mailbox is full"
  • Unable to send or receive new emails
  • Sync halts unexpectedly

Solutions:

  1. Log in to Webmail and delete old or large emails (check Sent, Spam, and Trash folders).
  2. Empty the Trash/Bin.
  3. Increase your mailbox quota via the Email Control Panel (if your hosting plan allows).

E. SSL/TLS Mismatch

Symptoms:

  • "Certificate mismatch"
  • "Insecure connection" or "SSL error"

Solutions:

  1. Ensure SSL/TLS is selected as encryption type.
  2. Use the official mail server name: mail.enmail.co
  3. Accept the certificate if prompted, or update your client to the latest version.

Step 4: Additional Troubleshooting and Tools

  • **Test via Webmail:**Log in to Webmail to check if emails appear and sync correctly. If Webmail works, the issue is with your local device or app.
  • **Check cPanel Email Trace:**Use cPanel’s Track Delivery feature to view message logs and delivery attempts.
  • **Use Email Setup Guides:**Refer to your hosting provider's guides for client-specific setup instructions.
  • **Check DNS Records:**Ensure your domain’s MX and SPF records are set correctly. In cPanel:

    • Go to Domains > Zone Editor

    • The MX record should point to mx.enmail.co

    • Add/verify SPF as:

      v=spf1 include:spf.enmail.co ~all

Frequently Asked Questions (FAQs)

**Q: Why are emails missing on my phone but visible in Webmail?**A: Check that your phone is set up using IMAP, not POP3. POP3 downloads and may delete mail from the server.

**Q: My sent emails don’t appear on other devices.**A: Make sure your email client is set to save sent items on the server (IMAP) and not locally.

**Q: Can I use third-party apps with my email?**A: Yes, as long as you use the correct IMAP/SMTP settings above.
