Email not sending can be caused by a variety of factors, from misconfigurations to server issues. Here’s how to troubleshoot and resolve common email sending problems:
- Check Email Configuration:
- Ensure your SMTP server settings are correct. They should match the configuration provided by your hosting provider (e.g.,
mail.yourdomain.comfor both incoming and outgoing servers). - Double-check the SMTP port settings. Use port 587 or 465 for secure SMTP connections.
- Verify the username and password for the email account.
- Ensure your SMTP server settings are correct. They should match the configuration provided by your hosting provider (e.g.,
- Verify Internet Connectivity:
- Make sure your internet connection is stable.
- If using an email client (e.g., Outlook, Thunderbird), try sending an email through webmail to determine if the issue is client-related
- Check for Blacklisting or ISP Block:
- Some Internet Service Providers (ISPs) may block outgoing email ports (25, 587). Contact your hosting provider to verify that your domain/IP isn’t blacklisted.
- Check if the recipient’s email server has blocked your domain.
- Check Mailbox Quote:
- Ensure that the mailbox quota for your email account hasn’t been exceeded. If it has, delete old emails or increase the quota in cPanel under Email Accounts.
- Review SPF and DKIM Settings:
- Incorrect SPF or DKIM records may result in email delivery issues. Ensure these DNS records are properly configured to authorize your domain’s outgoing emails.
- Enable Authentication:
- Enable SMTP authentication in your email client, ensuring that the server requires authentication before sending emails.
- Test and Contact Support:
- Send a test email to check functionality. If the issue persists, contact your hosting provider with detailed error messages or logs.
