Authorize not working in wp mail smtp

The frustration of authorize not working in WordPress's wp_mail SMTP!

Here are some common issues and solutions to help you troubleshoot:

  1. Incorrect SMTP credentials: Double-check your SMTP server credentials, including the username, password, and port number. Make sure they are correct and match your email provider's settings.
  2. Invalid SMTP host: Verify that the SMTP host is correct. It should be the hostname or IP address of your email provider's SMTP server.
  3. Missing or incorrect wp_mail_smtp settings: Ensure that the wp_mail_smtp settings are correctly configured in your WordPress installation. You can find these settings in the wp-config.php file or in a plugin like WP Mail SMTP.
  4. PHPMailer version issue: If you're using a plugin like WP Mail SMTP, ensure that it's compatible with your PHPMailer version. You can check the plugin's documentation or contact the developer for assistance.
  5. SMTP authentication issues: If you're using SMTP authentication, ensure that the authorize function is correctly configured. You can try setting the SMTPAuth option to true in your wp_mail_smtp settings.
  6. Firewall or antivirus software interference: Firewalls or antivirus software might be blocking the SMTP connection. Try temporarily disabling them to see if it resolves the issue.
  7. WordPress plugin conflicts: If you're using multiple plugins that interact with email, try deactivating them one by one to identify the culprit.
  8. Outdated WordPress or PHP version: Ensure that your WordPress and PHP versions are up-to-date, as older versions might not support the latest SMTP authentication methods.

To troubleshoot further, you can:

  1. Enable WordPress's debug mode to see error messages related to the wp_mail function.
  2. Use a plugin like WP Mail Log to log email sending attempts and errors.
  3. Check your email provider's documentation for specific SMTP settings and authentication requirements.
  4. Reach out to your email provider's support team for assistance with SMTP settings or authentication issues.

By following these steps, you should be able to identify and resolve the issue with authorize not working in WordPress's wp_mail SMTP.
