Email Errors – Cannot Send/Receive Emails
You may encounter issues when sending or receiving emails using third-party email clients such as Outlook, Mail for Mac, Thunderbird, and others. If this happens, you can visit how to edit your mail servers, or follow the troubleshooting steps below.
Troubleshooting Steps
- Verify your Incoming (IMAP) and Outgoing (SMTP) mail servers and port numbers.
- Check your domain’s DNS Records and ensure the MX Record is correct.
- Confirm your username (full email address) and password are correct.
- Temporarily disable firewall or antivirus software to rule out blocking issues.
- Check your internet connectivity and ensure ports are open.
- Perform a Telnet test to verify if your email ports are accessible.
Recommended Email Settings (for Vodien Email Hosting)
| Type | Server Name | Port | Encryption |
|---|---|---|---|
| Incoming (IMAP) | mail.yourdomain.com | 993 | SSL/TLS |
| Outgoing (SMTP) | mail.yourdomain.com | 465 or 587 | SSL/TLS |
Replace yourdomain.com with your actual domain name (for example: mail.vodien.com). Make sure SMTP Authentication is enabled in your email client and that you’re using your full email address as the username.
What Is Telnet?
Telnet is a computer protocol used to interact with remote servers. It allows you to test connectivity and check open ports between your device and your email server. Running a Telnet test can help determine whether your mail server ports are being blocked by your ISP or firewall.
Below are the steps to run a Telnet test for Windows and Mac.
Telnet Test on Windows
- Search for Control Panel and open it.
- Click Programs → Turn Windows features on or off.
- Check the box for Telnet Client and click OK to enable it.
- Open Command Prompt (search for cmd).
- Type the following command and press Enter:
telnet mail.yourdomain.com 465
If the port is open, you will see a blank screen or a successful connection message. If blocked, you’ll get an error message. Take a screenshot and contact your ISP (Internet Service Provider) to request that the port be unblocked.
Telnet Test on Mac
- Open Terminal (Applications → Utilities → Terminal).
- Type the following command and press Enter:
telnet mail.yourdomain.com 465
If the port is open, the screen will show a connection message. If blocked, you’ll see an error message. Contact your ISP to unblock the port and include the screenshot as proof.
