      • The recipient’s mailbox might be full and unable to accept new messages.

How Do I Fix Email Rejected by Server Step-by-Step Solutions

Let’s dive into the solutions for each potential issue:

1. Verify Your Login Credentials

  • Double-check that your email address & password are entered correctly.
  • If you recently changed your password, ensure all your devices and email clients are updated with the new credentials.

2. Ensure Proper Server Authentication

  • Access your email client settings and enable authentication for the outgoing mail server (SMTP).
  • Use the same credentials for both incoming (IMAP/POP) and outgoing (SMTP) servers.
  • Example settings for common email providers:
    • Gmail: smtp.gmail.com, Port: 587 (TLS) or 465 (SSL)
    • Outlook: smtp.office365.com, Port: 587 (TLS)

3. Check Spam Content

  • Avoid using spam-triggering phrases like “Congratulations,” “Free,” or “Act Now.”
  • Minimize the use of links and attachments, especially to unverified sites.
  • Use a professional email signature with verified contact details.

4. Monitor Mailbox Quotas

  • If the recipient’s mailbox is full, request them to clear space.
  • Ensure your own mailbox is within the allocated quota.

5. Check Black-listing

  • Use tools like MXToolBox or Spamhaus to check if your email server’s IP is black-listed.
  • If black-listed, contact your email provider or hosting service to resolve the issue.
  • Regularly monitor your server’s reputation to avoid future problems.

6. Configure Correct Email Settings

  • Ensure you’re using the correct SMTP and IMAP/POP server settings.
  • Use the appropriate port numbers as specified by your email provider.
  • Enable SSL/TLS for secure communication.

7. Validate Your Domain’s DNS Settings

  • If you’re using a custom domain, ensure the following records are properly configured:
    • SPF Record: Authorizes servers to send mail on behalf of your domain.
    • DKIM Record: Digitally signs your email to verify its authenticity.
    • DMARC Policy: Protects your domain from spoofing and phishing attempts.
  • You can use online tools like MXToolBox to verify your DNS settings.

8. Optimize Attachments

  • Keep attachment sizes under 10 MB or as recommended by your email provider.
  • Use commonly accepted file types like PDF or DOCX.
  • Compress large files using ZIP tools before attaching.

Advanced Troubleshooting

If the basic steps don’t resolve the issue, consider the following advanced techniques:

1. Update Your Email Client

  • Outdated email clients might have compatibility issues. Ensure you’re using the latest version.

2. Contact Your Email Provider

  • Reach out to email the provider’s support team for assistance.
  • Provide them with detailed error messages for quicker resolution.

3. Switch to a Different Network

  • Network-related restrictions can sometimes cause email rejections. Try sending the email from a different Wi-Fi or mobile network.

4. Use Webmail

  • If your email client isn’t working, log in to your provider’s webmail interface to send the email.

5. Test with a Different Email Client

  • Sometimes, the issue lies with the email client itself. Test your settings on another client such as Outlook, Thunderbird, or Apple Mail.

Preventing Future Issues

To avoid encountering the “Email rejected by server” error in the future, follow these best practices:

    1. Regularly Update Email Credentials:
      • Change your password periodically and avoid sharing it with others.
    2. Monitor Server Settings:

    3. Maintain Domain Reputation:
      • Avoid sending bulk emails without proper authorization.
        Use email marketing tools such as Mailchimp to manage bulk email campaigns.
    4. Educate Users:
      • Train team members or collaborators on email best practices to prevent errors and rejections.
    5. Implement Two-Factor Authentication (2FA):
      • Enhance the security of your email account to prevent Disallowed access.
